I have a program using two forms, a controlform and a displayform. The displayform contains a Thread form that does some calculations and then draws onto the canvas of an image in the diplayform (which is not visible). As soon as it does this the thread does not perform any further operations. If I replace the thread by a regular procedure the whole thing works fine, exceipt for the fact that the calculations take a while, and the program does not respond during that time.
Any ideas? Thanks in advance.
