kerfunkle3,

Three questions:

Have you set the listbox's ForeColor the same as the BackColor?
What version of Visual Basic?
Are you running a McAfee virus checker?

kerfunkle3,

If you are running McAfee(R) VirusScan(R) EnterpriseVersion 8.0i, then this
is a known bug.

McAfee has a patch at their site, but I don't have any of the details. I
know that Patch 9 fixed the problem for me a couple of years ago.
