Hello everyone I haven't posted in a while but I've been keeping up and reading. I have been having some problems with OS X. I assume its OS X but of course I don't know what could be causing it at this point. If this question can be anwsered without the need for my technical information than fine but I believe this stuff is important. I have a 15" Pb G4 ALU Rev. A 1.25ghz, 1.25g of ram, 80g HD, 64 vid, Logitech MX 1000 mouse and no external keyboard. I am using the latest Logitech Software and I have 10.4.6. The problem I seem to be having involves my mouse/trackpad. For whatever reason when moving my mouse alot of things don't register. Simply moving up and down with the mouse on occasion does not move the cursor. (Kind of like an old mouse with a dirty trackball) Also clicking rarely works, I have to click 5 or 6 time before it registers. I slowly came to the conclusion that it was simply the mouse had gone bad/dead(even though it had a full charge). This is when I tried the trackpad and noticed the same problems. No registering of me moving the cursor when sliding my mouse and the same problem when clicking with no response. One thing that is weird however is with my Logitech Mouse I have it set up so that two of the million buttons increases and decreases volume, well that has been malfunctioning as well, increasing and decreasing at random. Does anyone have any idea what could be causing this? It is extremely extremely annoying as you can imagine. Any help or thoughts would be greatly appreciated. I am wondering if the problems with the mouse could be creating the malfunction with the computer mono-button and trackpad. Since I cannot reproduce the results nearly as well or frequently as I can/do with the Logitech. Anyone have any idea what the protocol is for replacing/returning/fixing the logitech mouse. I would hope a 75 dollar mouse less than a year old would carry some kind of warranty.
