It's been a while, TWHL!
I'm replacing my system soon, and in doing so am moving from XP to Windows 7. I was wondering if there were any problems using the following tools under Windows 7:
Valve Hammer Editor 3.4/3.5
Wally
Pakscape (or equivelent pak explorer)
Half-Life Model Viewer (I know of at least two different ones, if either work it's fine)
Zoner's Compile Tools
Thanks.
