Hello,
I recommend you to use Windows XP for time being since, Windows Vista is new released and make softwares might not work with vista as they are not compitable to vista.
However, if you wish use the Windows Vista then I suggest you to make a note of softwares that are not working in Vista and then look forward for assistance of Particular software Manufacturer for patch of Vista driver or software to work with application.
So it is clearly an issue with softwares and not with Windows Vista. My personal advice you to start using Vista after 2-3 months as many software vendors started to release and work to develope their application software with Vista.
hmm, let me tell you further . You can visit and check out website of software vendor for any updates on Vista. This would help you. If you see any updates available, then please go ahead and try to download and install it. This would work !!!1
I am sure that this should resolve the issue for you.
if you need any further assistance you can mail me at thumuvikram@rediffmail.com. I'll be glad to help you.
Bye....
