yes I've seen it and live with it...but there is a way around that works for me. I use the Maxson browser (which is where this issue popped up first where IE never seemed to have the prob). Anyway try clicking on the reverse icon (lower right corner of screen) it should take you to reverse view and afterwhich time the space bar should work - until it gets stuck again (usually after using chat for me)
I also have a prob with full screen view (F11) with Maxon....but if I click on the in-game full screen icon (once to make it large then again to reduce) the F11 full screen mode works again.
Just my experiences....
Good luck
