Michael,
>Maybe it is contradictory to your original design, but what actually is needed in my case of ActiveX is just drawing ( the string and X,Y coordinates for baloon help are provided , but in this case probably it's my responsibility to kill it on mouse leave/mouse click or keypress which requires another function FoxGUI_KillToolTip )
Is the tooltip showing up, when you put the mouse pointer over the ActiveX? I just ran some tests and got an error each time I put the mouse over the control.
