The problem is with Win2K/XP and their communication library. It works fine on ME/98SE/98/95.
The library they use is 16-bit and very old.
There is hope. At least one of them is now running XP, so they will experience what we experience. Before that I don't believe anyone was running XP. Companies standardize on an OS and software and stay with it for a long time.
Older engineering apps are DOS based and don't always work under Win2k/XP. New versions of the same apps don't always support designes created on old versions (D0S) of the apps either. Then there is the cost of engineering apps. Yikes!
