I want to catch a repeated 500ms Form_Timer event while dragging the mouse. i.e. between mouse down and mouse up events. The Timer event is firing outside of the drag but not inside.
The reason for the Timer event is that the program does significant processing during the drag and often does not catch the most recent mouse location - after catching the timer event the program can poll the current mouse position. [For example the user may have dragged the mouse quickly into a position which is not reported by MouseMove and then hold the drag there]
Has anyone else had or resolved this problem?
I have experienced it on Windows XP Pro SP3 and Windows 7 Starter.
