Some of the things that are not in the Windows 3.1 version: long filenames, background colors, and enhanced metafile support. The individual windows have not been changed, but I have tried to improve the user interface in most of the modules, so you will notice differences.
Details of other changes can be found in the updated Help files.
If you use Windows XP and want Wincalc controls (buttons, scroll bars, etc) to have the Windows XP “look”, download this file (right-click and Save Target As). Extract the contents of this zipfile to the same folder where the program itself is found.
There will of course be occasional bugs. If you find things that I have missed, please tell me about them. Also send along any suggestions.
