One of my VFP 6.0 apps is causing probles for some machines. It takes over the cpu at 98-99 percent while on most machines it runs about 18-30 percent. The app has a main form that is maximized and a main menu in the main form. Giving focus to the main form lowers the cpu to 18-30 percent but as soon as you give focus to any other form it goes back to 99 percent. This is just on a few machines, runs fine on others.
