mouse wont 'wake up'

sorry for the silly questions im new but i have cordless microsoft keyboard and mouse but when my computer goes to sleep i click, roll.. my mouse and it only comes on sometimes! and i have to click like mad too. then i have to hit that button on the transmiter thing to get it to wake up!? any ideas is it the mouse itself flaw(not batteries) or a setting...

My mouse used to do this, too (standard apple wireless). When the comp goes to sleep, usually the bluetooth sleeps as well. This includes your mouse. Mine has taken up to 30 seconds to wake up before. If it takes much longer, you may have a faulty mouse.

hmm i was starting to think that its faulty. ill have to wait 30 seconds to see, i geuss ive been a bit impationant shaking it etc hahaha breath..clam thanks
