Comment 18 for bug 239462

Further to my previous comment, #15:

After the pop-up has been "popped down", redisplay of the pop-up needs to be disabled until the mouse pointer moves off the object in question. Moving the mouse pointer back over the same object would re-enable pop-up display. In this way, the end user may redisplay the pop-up if required, but won't be annoyed by the pop-up reappearing undesirably, as it does now. Fairly intuitive, I think. But of course, if the pop-up display time responds to mouse movement, such behaviour would only be required infrequently.

To this end, it might be appropriate to maintain two flags for controlling pop-up behaviour internally: a flag controlling whether the tool-tip should be popped up and a flag controlling whether the tool-tip should be popped down. These would be suitably set or cleared at mouse-enter-over-object, mouse-hover-over-object, mouse-move-over-object and mouse-exit-off-object (or whatever the proper terms are). I leave such detail to the implementer -- only a suggestion.
