I'm baffled by not ever seeing a thread about this and starting to think maybe it's just me, but it happens on both computers I have Hammer installed. When I open my model viewer, it's set to TF just like always but in order to see anything I have to switch to hl2 and then back to TF. I just so happened to figure that out early on and have always done that work-around to bring up the TF models. Is this how it is for everyone? This doesn't bother anyone else? I'm just surprised not to see complaints about it. I think it could even go into the letter to valve... I hate to do all that clicking around in the drop-down list - major speedbump IMO.
