I am running a PM G4 1.25DP MDD with X.4.11. This is a clean install and I am in the process of resurrecting this system from extended storage. I have replaced the power supply, the PRAM, and both hard drives (hence the clean install). This system is pretty vanilla as far as the software goes and is sporting the stock 2G RAM.
Sometimes while using the system and moving windows around, the mouse will freeze up. Nothing I can do will result in the mouse moving or responding. When this happens, the keyboard continues to work and the system otherwise seems fine. The only known fix is to hard restart my system. The mouse is actually a very reliable, tried and true MacAlly iBall and is my only easy option for a 'mouse'. I am am doubtful the iBall is the issue based on its historical performance. It is plugged into the back of my Cinema Display. I do have a BT Apple keyboard and mouse buried around here somewhere but I believe they have an issue with them based on the known history. Before I connect a possible-issue-BT-mouse to a possible-issue-system, I want to resolve the known reliable-working-trackball with the possible-issue-system.
So, could there be an issue with my Mac itself? And if so, what can I do to diagnose the problem?
