well this is new and I dont like it..

I got into maya and start doing something (no matter what) and all of the sudden my keyboard stops working (alt still works for moving around) but W E and R stop working for manipulating objects so as any other keys...

then if I minimize maya, I cannot click or do ANYTHING for about 15-20 seconds... my PC is working but does not let me click on anything

after that it starts back up and everything is fine again.. it happened to my the other day too and today 3 time in a row

BTW I have a cordless Logitech keyboard and mouse combo...

thanks!
