If you use System Monitor to monitor the number of threads (System\Threads) you will see that each time the dialog is opened and closed the total number of threads increases by two, so paint_proc is being called from first one thread, then 3, then 5, etc. I think you need to provide some method of exiting the thread, and resetting the necessary variables, when the second dialog is closed, or create the thread only once, and thereafter use SuspendThread and ResumeThread to control it.
