Disappearing Text in Windows Vista

[J. W. T. Kottekoe]

I have encountered a bug that I can reproduce in a simple test application
that is constructed entirely in the designer within Visual Studio 2005, with
not one line of code written by me. Briefly, all the text in a TextBox
disappears whenever the mouse cursor enters or leaves the box. I've only
seen it under a very special set of conditions, summarized below. Has anyone
else seen this?

======

Details:

My test machine has insufficient graphics to run the fancy graphics features
of Aero, and only if I use the "Windows Vista Basic" theme, rather than the
"Windows Classic" or "Windows Standard".

All that is required is a TextBox with at least one ScrollBar, inside a
SplitContainer on a TabPage. If any of these elements is missing, it works
fine. A work-around is to call TextBox.Invalidate() on MouseEnter and
MouseLeave, but this solution is not entirely satisfactory.

I would appreciate any help you can give me.

I'm just getting started with Vista development also, so I can't
specifically answer your question. But there are some very good docs to be
found here: http://msdn2.microsoft.com/en-us/win.../aa904950.aspx

In case of Minimalism, break Philip Glass.

Kevin,

Thanks. I will try the MSDN forum, per your recommendation.
