Hi Slayerx,
In my months of testing Vista and now with Home premium I have had two incidents of Vista hating my programs - or rather the programs hating Vista.
Blue Soleil bluetooth software - causes a blue screen loop
Sony Ericsson PC Suite - simply will not install. I emailed Sony and they say they have no plans for a Vista version in the immediate future.
I will also add that I could not register my Adobe Photoshop Album, however this was resolved by running the registration by right click run as admin.
That is all. Everything else runs fine. Although I have to admit, I really never have much on my computer anyway so I have not done extensive individual software testing.
