Simon,

>I read the VFP documentation but I could not tell if the timer event can be trigger while in the timer event or is it disabled until the timer event completes. I am trying to trace down a strange experience where the debugger shows a timer control disabled and the timer event still occuring (There is only one timer on the form).

Yes! it does. I encountered that a timer - esp. when interval is short - fires a second time even if it should only once.

What I do ALWAYS is :

PROCEDURE TIMER
local ln_WasInt
if this.Interval = 0
    return
else
    ln_WasInt     = This.Interval
    this.Interval = 0
endif

.... do my work ...
 

this.Interval = ln_WasInt
ENDPROC

And since I do this, never had problems with timers anymore
