>What I found that MouseDown will fire AT LEAST once for each mouse click or dblclick. The speed in clicking varies the results. For example if you left click on a node and hold the button down for one second Click and MouseUp will not fire. Depending on the speed of a dblclick if DblClick will fire or not. NodeClick seems to be the second most relible method if fires 99% of the time click and dblclick about 50% of the time as I vary the speed of clicking with the mouse...

John,
Right mousedown always fires at least once. Holding for one second or more still fires click and mouseup. However if you mousedown on anitem and move to mouse to another place and mouseup, click doesn't fire. It's similar behaviour with other controls. ie: Mousedown on a button move the mouse to somewhere outside the button and hold for sometime before releasing. Click doesn't fire. It's also not a VFP issue and occurs for all windows buttons.
Nodeclick OTOH fires frequently and actually not a click event as it name refers. Nodeclick code is run even if you use only keyboard, and somewhat correpond to gotfocus :)
When a dblclick occurs, click occur at a HIGH chance (apprx 80%) and code in click doesn't suppress dblclick code running despite docs say the reverse.
What really you want to do ? I usually only use Nodeclick in treeview.
