Missing caption in grouped taskbar buttons

[Peter Franks]

I'm experiencing a problem w/ my application where, when taskbar
grouping is enabled, and there are sufficient other programs running
that grouping is active, if I run my app, then display the help file by
using:

System.Windows.Forms.Help.ShowHelp(this, "app_help.chm")

I experience strangeness in the grouped taskbar buttons in that my app
and help window are grouped together AND (more importantly) the taskbar
button caption is _blank_ (clicking on the button displays the relevant
task captions).

Anyone else experienced this behavior?

Running the application and then manually opening the help file (from
Explorer) doesn't exhibit the problem. Apparently ShowHelp does
something strange. Using ShowHelp(null,...) throws an exception.

Thanks for the link.

Unfortunately, in my situation, changing the FileDescription ([assembly:
AssemblyTitle("xxx")] doesn't fix the problem...

Strange.
