Does the price include both Mac OS X and PC versions?

Yes.  The price on the ordering information is for a package containing both versions.  You should provide both versions for students, teachers, and other users receiving personal copies, in case their own personal computers are different from the kind of computers at your site.

Why is the license written to cover the Package and not the individual files?

That allows the license to include any files we add to the Package later.  We would be able to simply send you the additional files, without requiring a new license agreement from you.

How is the new PC version of Green Globs & Graphing Equations different from the previous version?

The new version is written in Visual Basic 6, which is 32-bit, so you can use long file names.  (Sound is restored, also.)  The menu options and buttons from the previous version are still there.  If you have experience using the previous version, you can use this version the same way.  Screen displays that include a graphing grid now have a larger window size that uses most of a screen with 1024 by 768 resolution.  Technically, the program assumes a DPI setting of "normal", which is the default.  (DPI is an advanced setting under the display option in the Control Panel.  If you're not familiar with it, your setting is probably "normal".)

There are some small changes (e.g., in Equation Grapher, you can now have up to ten graphs instead of five).   The teacher’s manual has been revised.  There is improved formatting on some of the student worksheets, but the content is the same as in the previous version.

For the PC version:  will the Records files (and List files containing lists of them) from the previous version work with this version?

For the Mac version: will the Globs/Tracker Records files (and List files containing lists of them) from the previous version work with this version?

The previous Globs/Tracker Records files and List files are compatible with this version.  When you open any Globs/Tracker Records file (or List file) in any folder, OS X will automatically start your latest version of Green Globs & Graphing Equations.

Will the new Mac version of Green Globs & Graphing Equations run in OS X Leopard?

Yes, it has been tested extensively in OS X Leopard and Tiger.  It should run in earlier versions of OS X, but it hasn’t been tested in them.  If it doesn’t run in your version of OS X, we will refund your purchase price.

How is the Mac OS X version of Green Globs & Graphing Equations different from the previous version?

The previous version has been revised and updated by the authors to run under all versions of OS X, but the menu options and buttons from the previous version are still there.  If you have experience using the previous version, you can use this version the same way.  The appearance has been updated to OS X, and a larger window size now uses most of a screen that has 1024 by 768 resolution.  (Smaller window sizes are still available for lower screen resolutions.)  The new version can handle longer file names, and there are some small changes (e.g., in Equation Grapher, you can now have up to ten graphs instead of five).   The teacher’s manual has been revised for OS X.  There is improved formatting on some of the student worksheets, but the content is the same as in the previous version.

What if something happens to the software you send us by email?

If something goes wrong with the email or the installation (or even anytime later), contact us, and we will re-send your files.

What if there is an error in the software?

This Mac OS X version has been tested extensively in OS X Tiger and Leopard, and there are no known program errors. The PC version has had similar testing, and there are no known program errors. If you encounter a program error, please report it, and include in your report as much diagnostic information as you can. With your help, we will do our best to identify and correct errors. 

We can send you an upgrade to the Green Globs & Graphing Equations application file without affecting any of your license information or student work saved in Records files. You would only need to replace your application file with the updated version.

This Mac version of Green Globs & Graphing Equations runs as a carbon application in OS X.  Will you have a Mac version which runs as a native OS X application?

The program was written in FutureBasic, and there has been a major effort to provide translation from FutureBasic to C, so that the program could be compiled to a native OS X application.  There hasn't been time yet to try this with Green Globs & Graphing Equations, so we can’t answer this question.  Anyone who signs up for the mailing list will be notified if a native application becomes available.  The new version appears to run well as a carbon application in OS X.
