Tools not working?

Okay, a couple days ago I was enjoying Garry’s mod, then out of the blue, the tools stopped working.
Heres a picture of what it looks like: http://s1092.photobucket.com/albums/i401/ZeKurt/?action=view&current=gmod1.jpg

Now, when I click the buttons, as of “Construction”, for example, It just changes color. From grey to white.

Nothing comes back. This is really annoying and if I can’t fix it, I wish I could get a refund. :frowning:

Might be a bug with the Mac, they aren’t meant for gaming and aren’t fully optimized into source. To make it clearer - Get a PC.

Defrag + check consistancy.

This belongs in help and support, but I have never seen this before. The last thing I would do is reinstall gmod.
