SOLVED -- MessageBar markup doesn't work in Vista

I have a customer with new PC that has Vista Home Premium.

When he runs my software, all seems OK except the CommandBars.MessageBar.Message displays the markup text on the screen.

With my PC (and other customers) this MessageBar draws the panel nicely (ie. the markup works OK).

Any idea why this Vista PC should not work with the Markup ??   The MessageBar just shows:  "<Stackpanel orientation='horizontal'><... etc

The solution is that text to be displayed included one of the following "special" characters that upset
the XML markup:  < > &
Fixed by swapping these characters for lwegal ones, or replacing with escape codes.

A thought:

If the markup that you are trying to display has any dynamic text, its possible that the problem isn't with Vista, its just a coincidence that the problem is appearing on that customer's computer. The problem in that case would be that the dynamic string that is unique on that computer contains a reserved XAML/Markup character. Make sure that you are escaping your text that will be displayed before adding it to your markup string. See this post:

I bet you are correct. Thank you.

The text being displayed is the user Company Name, and I guess they have used < > or & in their name.

I have now escaped those chrs and expect that to solve the problem.   (I found that chrs ' " ? did not seem to upset the XML)

As often the case, I did not see the answer because I was looking in the wrong place.
