Assertion Error Message

Mon, 15 Jan 1996 20:47:10 -0500

I'm using the Cornell W0.84b7 version of CU-SeeMe under Windows 95. On
occassion I have listed in the Participants Sending list a name that has no
screeen showing <not my own>. When I click on the name so as to send it to
the Participants Sending (Not Showing) list below, I get the following
error message:

Assertion Error
Null Assertion()
File: c:\e\cuseeme\r084\core\video02.c
Line: 424

The name refuses to be moved, the user's screen still remains unseen but
still counts as one of ones allowed open in the max screen # limit.

Anybody else seen this, have a solution?
