This bug shows up when running Microsoft winhlp32.exe under Wine. I tested the
versions from Windows 98 and XP.

Some help files contain links which when clicked open a pop-up box. The box has
a semi-transparent shadow effect to the right and below, achieved by rendering
alternate pixels of the shadow area black.

In Wine, sometimes the shadow is rendered entirely in black. Whether it's
rendered correctly or in black doesn't seem to be consistent; you can click a
popup link many times and sometimes the shadow is rendered correctly, other
times in black. Or on a page with multiple popup links, clicking on different
links gives a different result.

Try viewing the attached FACTS.HLP in Microsoft winhlp32 under Wine. Various
pages of that help file have popup links.
