Before I read your reply I tested another thing: I dropped a regular timer from the component palette onto the form intending to use that instead of FpTimer. So I made an event function by doubleclicking the event as usual and added the same call there. I set the new timer to disabled by default so I can enable it on successful port open like the FpTimer. Once all that was done I again stepped through the application with breakponts in both event functions and amazingly the FpTimer event now fired! And after it was done the new timer also called its event... In fact it now seems to work where it did not before. So next I *removed* the newly dropped timer and its references in the code and now the FpTimer still works. How very strange! Concerning calling CheckSynchronize I do not really know where it can be done... I think you do not mean that I should put a timer on the main form and then in its OnTimer event call CheckSynchronize? This program is a GUI application and I do not know where one could put a call like that. -- Bo Berglund Developer in Sweden _______________________________________________ fpc-pascal maillist - fpc-pascal@lists.freepascal.org https://lists.freepascal.org/cgi-bin/mailman/listinfo/fpc-pascal
