Hi!

Your description is rather sketchy. If you have a .pjd to share (with
sources that have hand coding in them because they cannot be
regenerated), it would help. It takes much less time to ferret out the
problem and fewer exchanges back and forth in posts!;)

My first question would be are you using sizers? If so, and the
RichText is contained in a sizer, you need to call Layout() for the
sizer after the Show().

E.G.:

MyFrame::ShowErrors()
{
ErrorText->Show();
MyFrameSizer->Layout();
}

You don't have to actually name the sizer (I do as a matter of course
for all my elements for readability and for easy access). You can just
call MyFrame->GetSizer()->Layout(). I just find this unnecessary
indirection so I give the sizer a Member variable name. It is, of
course, your choice.

BTW, why a wxRichTextCtrl for a simple error window? RichText is more
for formal editing/word processing display with images, icons, varied
fonts, and varied placements. A wxTextCtrl would do quite nicely with
less overhead, jmtcw!;)

You need to call Layout() on the wxDialogBox after calling Show() or
Hide(). This tells the sizer to put the wxRichTextCtrl where it
belongs, or to re-shrink the dialog box when concealing it.
