Hi, since a couple of days my Macbook keyboard is acting very strangely. When I turn my Mac on, every second time (!) the permanent shift key and the Num. F6 key are activated, but the keyboard reacts as if they were not. When I deactivate them it reacts the other way round. It requires a restart for the keyboard the act normal again. The next time I start my Mac it is wrong again. Hope this description was understandable. Has anybody experienced the same or something similar? Will 10.5.2 be the fix for this? Thx to all!
