I am using PS6.0 on a Win2k machine with an Athlon 1.4Ghz and 1.5GB RAM.

When I have text selected for editing, the CPU usage of Photoshop goes to 100% and stays there. This seems unreasonable considering the fairly powerful CPU. Worse, my system tends to lock up (overheat) when the usage is maxed out for more than a few minutes, so it's almost impossible for to do any text formatting etc.

Any suggestions?
