Hi!

After some experimenting I did figured out that the timer event, event after the timer is disabled, continue to fire! It looks like VFP cached the timer events during the form resizing internal processes, then fire the timer event as many times as needed for the passed period of time. To fix this behaviour, just use following very simple thing:

* Timer event
IF !MDOWN() AND this.Enabled

this.Enabled = .F.
MESSAGEBOX("HI")

ENDIF


Now message box appears only once.

> MESSAGEBOX("HI")
>ENDIF

>And the timer is enabled on the resize. Works great in most situations.

>But, when i resize the form and hold it in the same position for 4-5 seconds before releasing the button on the mouse at that same position (at which point the timer will hit) it actually runs my code (and displays my messagebox) multiple times. The longer I hold the mouse before letting go the more times.
