From what I've read in my research on Al Gores Amazing Internet, this is a common problem... that the left arrow button doesn't work when attempting to access the info screen when upgrading talents, force abilites, etc.

Does anyone have any further information on this? Is there going to be a patch to fix it, or does someone know how to fix it?

Unfortunately I can offer no other info. But try posting your problem here at Lucas Arts Tech Support Forums (http://forums.lucasarts.com/category.jspa?categoryID=11). I think you may be able to find somebody there with the answer to your problem.

Best of luck and welcome to the forums!
