Well, I believe tetsuya_shino, because tgf is a old proram. But my advise it is not only for tgf, it is for all programs. If only tgf would have small bug, then you i woul be stupid to change. I'm talking about overall.
I have proven new mathematic formula to be true...
I used to have this problem when using TFG on XP a few years ago. The problem is now none existant, but I can't say I remember how I fixed it... Sorry.
Downgrading would only improve performance actually, because XP can deal with the fact its ugly while Vista will waste CPU and GPU power in failed attempts to be pretty!
I bought a new laptop and my Vista is fine, i have the pro addition, the only thing that really bugs me about vista is dam sound recorder its like they have took a hugh step back, i thought it was a joke when i first found it lol! i have since downloaded a copy of xp sound recorder
