>I think the issue is with Wait Window Nowait not with MouseEnter or MouseLeave, as as soon as you move the mouse the wait window closes, so you need to stop your mouse movement just when the wait windows appear, which must be why you see it working occasionally, ie try this:

Wait waits for a click or keypress, and shouldn't be sensitive to mouse movements. However, it can interfere with MouseEnter, as it's a window unto itself, and its (implied) .show() may disturb the events, your form may briefly lose focus and generally gets in the way. I suspect the same with your
ACTIVATE SCREEN, which would fire .deactivate() of the current form. Even though are supposed to happen after the observed event occurs, they may influence the events which should happen next.

For tracking stuff like this, I don't even trust the debugger, as it's a set of windows unto itself, and interferes with activate/deactivate because it takes focus. I'd rather do some silent logging - event tracking, coverage, my own logging, debugout - whichever is handier at the moment.

>>Hi All
>>Is there a trick to get MouseEnter and MouseLeave to work on a Textbox?
>>If I use the Wait Window Nowait function in MouseEnter nothing happens most of the time when the mouse enters. Very occasionally it does, but very intermittant.
