Not quite:
we already have tooltips on the toolbar. And for some reason, windows
only creates one tooltip control per thread. Since both the view and the
toolbar are in the same (UI) thread, they share the same tooltip control.
It flashes because:
1) tooltip gets shown for the view (e.g. revision node)
2) tooltip is shown big enough to cover the toolbar
3) tooltip control asks the toolbar whether to show a tooltip
4) toolbar says no - the cursor isn't over the toolbar
5) tooltip control destroys the tooltip which is already shown
6) start at 1)
The only way to overcome this problem is to write our own tooltip
control. If you know of another way, please let me know.
