Hotkey problem

Im trying to use fraps to record in Gmod, but everytime I press F9 to record, it loads up the Bigcity map. Now, I remember something about that map saying that it did something with GM_Construct, but I dont think fraps has anything to do with that.

I believe you load your last save with F9, and that you maybe accidentally saved while being in gm_bigcity once.

Change the record button to something else.
