RichTextBox Control Captures Shortcut Keys in Regular Windows App but Fails to Capture in an MDI App

[TCook]

Hello All,

First, I apologize for posting this to so many newsgroups but I wasn't sure
which newsgroup was most appropriate nor which newsgroup would most likely
have subscribers that have done this or would have the answer. That said,
below is a description of my problem:

If I create a standard Windows executable in C# or VB.Net and place a
RichTextBox control on the main form, the control captures standard shortcut
keys as expected (i.e. Ctrl-V, Ctrl-X, etc.). However, if I add an MDI
parent form to the project, make the original form a child form to this
parent MDI form and display the original form, the RichTextBox control no
longer captures these shortcut keys.

Can someone please tell me what is necessary to correct this behavior?

Thanks & Regards,

TC
