I have a 6 month old Powerbook G4. I purchased it at the end of June last year.

Today it has been giving me some real problems, which I cannot seem to find a cure for.

It's a G4 867MHz model, 12". Running 10.2.8

The problems I have been having are as follows.

Sometimes my iChat (1.0.1) will crash on me. And when it crashes, it locks up the entire right half of the taskbar. Meaning I cannot click the iChat dropdown, airport extreme dropdown, volume dropdown, time or battery dropdowns. I cannot figure out what is causing this to happen or how to fix it.

I don't think it's a memory problem, as all I have open at all times is iChat and MSN. I do webdesign and graphics, but I barely have photoshop open.
And I don't think it's a problem on driver space, since I have used only 8GB on my 40GB Harddrive.

Any help would be greatly appreciated.

Thank You.
