Typing problems and selecting problems.

Hi. When I try to select anything in garry’s mod holding Q and left clicking. It makes the other bar say like Half life 2 and if I click on Team Fortress 2. It will make both blue and I can’t select the other.

And also. If I try to type the letter a it will do the following in the search or chat for Garry’s mod.

Example of what it should be: “How do I spawn a car?”
What it will end up with. “ar?”

It resets after the letter a. Can anyone please help with this. It really sucks.

Bumping this. It is still happening and I need help with it.
