Occasionally when I start up Illustrator for the first time in the morning my space bar and shift keys will not work. I CAN type capital letters with the shift key, but I can not constrain proportions when I resize something with the shift key. Also, my space bar will not activate the hand tool. I can pres "h" and get the hand tool. I can also type spaces with the space bar, but no hand tool.
Restarting the computer seems to fix the problem. Ive been using this program for 6 years and I just started getting this problem a couple of weeks ago. I haven't changed computers recently either.
Anyone else had this happen to them?
I believe it is owing to some errors by the OS during saving when you close down. Sometimes, it is enough to restart Illy, or the computer, sometimes it is necessary to delete/move the preferences, to get things to work again.
