Got Packard Bell TJ66 with OS Version: Mac OS X Snow Leopard 10.6 (10A432) 3.5 Universal Install, 4 GB Ram, Intel Dual Core T4400.

Mouse freezes unpredictably just after the wheel under the grey apple in the white screen leads to the next step and the desktop appears, but not always. Many other times boots normally. When it does not load, no mouse can be found in System Preferences--Mouse.

This leaves me with the trackpad alone, which is sometimes uncomfortable.

As told, this does not happen always. Many other times (about fifty-fifty or so) it loads fine and mousepointer works when handling the real mouse.

Any idea on this? Would deactivating trackpad solve this issue?

Help is much apreciated. Regards...
