I am running Vista Ultimate on MBP 2.4GHz. Yesterday, I bought an Apple Wireless Keyboard to use while the MBP sits on my Griffin Elevator. I also have a small logitech bluetooth mouse that I had been using with my PC laptop. While the logitech BT mouse had no issues pairing in Vista, I did experience two issues with the Apple keyboard. Here is how I addressed each issue (in Vista): 1. Bluetooth properties window disappears before I can enter a passkey into the keyboard. Frustrating because you must have a passkey for the keyboard to work. Fix: removed all my BT devices and added the Apple keyboard first. This time it let me type in the passkey and pair. Then I added the mouse, which obviously doesn't require a passkey. 2. When rebooting into Vista after using Mac OS X, the BT keyboard is no longer paired and no longer shows up in the BT wizard. This has happened twice this morning. Fix: turn off the Apple keyboard (switch is on the back) for a few seconds, turn it back on and re-search. You will need to repair the device. Annoying, but at least it pairs! Please post any other lessons learned here! Apologies if this post duplicates another -- a forum search didn't turn up anything obvious.
