I have a small VB6 application that does not react any more after approx. 50 executions. Only reboot of PC is helping. Seems to be a problem with cleaning up variables, etc...
This small app is running in the task bar and acts as a DDE server and waits for DDE commands. Then it searches for a specific Window on the screen, opens it and then making a similar DDE call as well. That's it.
