Strange keyboard/mouse behaviour

Hi there!

So i just installed the latest SH5 with Steel Wolf and patch. Everything was going just fine and then has i was trying a new mission, i can't use my "f: keys anymore and the awds keys don't work and i can't plot a course etc. Obviously i can't walk around anymore. Don't know what i touched here or whatever. Did search but can't find anything in here.

any ideas?

Tx, Alan.
