I really hope someone can help me before I throw my computer out the window. My system preferences window is stuck on the left side of my screen. I can only view half of it and can't move it. I also can't select anything on the sys pref window. Please check out the image. Somehow I opened up Mobile Me and got a separate pop up and I am unable to close or move that as well. I have OS 10.5.8 and using a Microsoft Natural wireless 6000 mouse. I searched this forum, but only found 1 slightly similar issue. The solution was to delete the com.apple.dock.plist. I tried that and restarted, but nothing changed. In case it will be helpful, I have included the chain of events that led to this problem: - First, my mouse stopped letting me double-click to select a word or any text. I altered the settings and things just got worse. -I reset it to default set up and restarted. That didn't change anything. -I opened the system preferences window again and it was unresponsive. I cannot click on anything. When I click on my mouse icon, a menu appears with a "Remove" option. -I repaired my disk permissions and restarted. No change. -I opened the sys pref window and moved it. Then the cursor was stuck to it and as I moved the cursor around, the sys pref window moved with it. I couldn't click on anything anymore and had to do a hard restart. When it came back up, I clicked on restart and waited. -When I opened the sys pref window again it was stuck on the left side of my screen and only half visible. Since then, I haven't been able to click on it to move it or select anything. I have no idea how I was able to open Mobile Me. -My computer is pretty much unusable until I can solve this. My mouse is so messed up that I can barely use it. I will extremely grateful to anyone who can help me figure this out! Thank you!
