I wrote a C program and compiled as win32 application, it worked fine on win98. I tried it on NT 4, it worked too. Will it be able to work on Win2000 and XP as well? Sorry, I'm still using Win98 and NT 4, thus have no way to test my program on Win2000 and XP. >XP is actually NT 6 >Win2000 was NT 5 > >XP has the new UI, which is mostly the cause for the sluggishness.

In my >opinion, XP is the worst OS since Win95. _________________________________________________________________ The new MSN 8: smart spam protection and 2 months FREE* http://join.msn.com/?page=features/junkmail -- http://www.piclist.com hint: PICList Posts must start with ONE topic: [PIC]:,[SX]:,[AVR]: ->uP ONLY!
