The main problem is this is a old program made for Windows 98 a 32 bit OS issues began showing up when users started moving to 64 bit.
One of my engineering programs started to lock up when I updated to Windows 7 Pro 64-bit, and I had to run it in the XP compatibility mode. So Microsoft changed something when they went to 64-bits.
In this case it was a $500 development program back in 2000. That company was bought out by a competitor, and the product was killed off. The last time I checked the alternative costs several thousand dollars.
The same thing happened with Quattro Pro running on Win 7 Pro 64-bit. It runs in the XP compatibility mode, but even then sometimes the embedded macros do not save all the way down a column on a very large spreadsheet.
Of course the fix is to buy the new version of WordPerfect office, but I'm resistant to spend money to replace something that has been working fine all along - sort of like my X10 system.
