Stuck Camera

Okay this probably is the most easiest thing to fix, but…

All of a sudden when I alt-tabbed back into Hammer, I was stuck in a permanent Camera mode, no matter what tool I pull out, everything moves around like I’m using the Camera tool. I tried restarting Hammer and it is still the same! Please help!

Press space.
if it doesn’t work
Close hammer.exe with task manager, and relaunch it.

Kind of strange…

As soon as I posted this thread it started working again.

Thanks for your help though, I will remember this for next time this annoying problem comes.
