Hi! I've been using ATT for some years now and it's an essential tool to me. I never had any problems, until Windows 7 came up. At first, everything ran fine. I have 5 PCs by the way and they are installed and updated as equally as possible. I use Win7 Pro x64 SP1 and the most recent Beta of ATT. Every one or two months I reinstall the PCs to get clean status again and the most recent updates. The problem with Steam and ATT's Force Triple Buffer came quiet suddenly. I spent some time to analyse this matter. If I have a profile in ATT for Steam.exe with activated Triple Buffers, Steam crashes soon after entering the password. It seems to came around after a certain patch level of Windows or so, because the old PCs run still fine with that settings and every fresh installation has that problem. But the really weird thing is that Steam even crashes if I start it directly without using ATT's profile! To get it working again, I have to deactivate Force Triple Buffer, delete the profile for Steam.exe or unload ATT. Thanks in advance for some advice.
