Microsoft is notorious for having drivers, patches you don't get unless you call it in.
2. Call it in.
I've had MS replace such things when they don't work. MS seems to want to protect their mouse and keyboard line from bad press. Wish they would work as hard on the other products.
I have the MS Keyboard Elite for Bluetooth (I have the mouse too, but no issues with that) and recently purchased an Apple Mac Mini (with Mac OS X v. 10.5.2). I don't have a problem pairing or connecting, but when the keyboard "goes to sleep" after about five minutes, it loses connection. The mouse does the same thing, but using it wakes it up and it reconnects on its own. The keyboard, however, does NOT reconnect automatically when woken up. I have to go through the reconnect process. I looked for a driver online but it seems as though there isn't one for my OS version. Any ideas on what i can do to rectify this situation?
