I've a problem with PS7 (and to a lesser degree 5). When clicking on a new tool to select it, PS7 acts as though I've kept my finger on the mouse button and displays the hidden tools that correspond to the particular tool that I have selected. Clicking on the required tool then makes the hidden tools disappear. With 5, the hidden tools flash up very quickly, then disappear, leaving the correct tool selected. I thought it was a mouse problem as I've just installed a MS wireless mouse with Intellimouse 5 s/ware. But returning to my previous setup still left the problem. I'm running XP Home on an Athlon 2400+ system with 768MB ram (recently upgraded from 256). Any help? Si.
