We are embedding a DWF Viewer Control onto a windows form through visual studio.
It works fine except the toolbar buttons sometimes dissapear when moving the cursor past some of the buttons. When I say dissapear, I mean they are not refreshed or redrawn. They only re-appear after causing a refresh of the entire control by invalidating it (e.g. maximizing the form). This is very frustrating for users when the buttons randomly not draw themselves.
One solution we found was to not apply visual styles to the application, but this makes everything ugly. And I am unsuccessful in disabling visual styles for just the viewer control.
Does anyone have any solutions to this problem or experienced something similar?
I have attached a screenshot showing the problem...
