Randy,

Thanks for the answer. I think i will disable the timer just to be sure.


>>In a VFP 8.0 application (.EXE) we have a timer that calls a method in an object. Same method in same (instance of) object can also be called by clicking on a button in a screen. If they would be called exactly at the same time, would that be a problem?

In the situation where the timer "fires" while the method is already running, the timer() event code is going to be deferred until you get to the next wait state, unless your method code issues a DOEVENTS statement. Presumably you would not do that on purpose, buf if you did, the call stack might look like:
