Gregory,
Thanks for that I hadn't entirely appreciated that the MouseUp and MouseDown caused 2 different sets of actions.

>>Just in case anyone was interested the best combination seems to be

>>* MouseDown()
>>Lparameters nButton, nShift, nXCoord, nYCoord
>>
>>*-- This just stops the selection/deselection.
>>*-- However the RightClick still runs.
>>If nButton = 2
>>	NoDefault
>>EndIf
>>
>>* RightClick()
>>ThisForm.cmdeMail.Click()  &&Perform desired RightClick action.
