Bug with Grenade?

[Forks]

For some reason I'm unable to select/switch to the grenade and throw it. I'm assuming it's bound to my detonator button, which is the Right Mouse key and it won't throw.

After selecting 1 through 5, I'm unable to use my blaster.

To switch betweeen grenade types press the 'Q' button. Or you can map the keys as you wish under otions then controls. Personally I prefer 'G' to throw grenade and right mouse button to walk forward.
