I just got the MagicTrackpad a week ago after using the trackpad on my MacBook Pro for a while instead of a mouse. I have it set up on my desktop with an external monitor and wanted to try out the multi gestures with using a trackpad. I found I loved it and bought the Apple Bluetooth MagicTrackpad. But for the past two days, I get a weird problem. I can't duplicate it, it just happens out of no-where. For some reason, when using it I'll get it stuck like the mouse button is down...and it won't click on anything. Won't click on windows, won't activate the Dock (have it auto-hiding) when I put the pointer down there....nothing. And using the connected USB mouse won't do anything either. I've even logged out of my account and can't use either the mouse or trackpad to click on anything at the log-in screen...even though the pointer moves fine. I've tried turning off the trackpad and gain control back with the USB mouse, nothing. I eventually just have to reboot the entire machine to "clear" it. Here's the weird thing too, one time it got stuck on dragging a window. I couldn't stop it from dragging the window around. I clicked and tapped and tried the USB mouse...it wouldn't let go of that window. After hitting ESC a few times, it let go of it. Quitting the Finder doesn't do anything ether. And again, I'm not losing connection with BlueTooth to the TrackPad at all. Not getting any errors. Nothing's even showing up in the logs. Also, i can right-click with my mouse or use the right-click options on the TrackPad to bring up a contextual menu or activate menus in the menubar, but can't left click on them when it gets like that. Luckily right-clicking on them will usually activate a menu item too, so i'm able to hit reboot easily. WTF?
