Combo box controls in Windows Applications render list items blank

[Guest]

Several of our windows applications are rendering the items created in
controls like ComboBox controls as blank. The items are actually in the
collection but the window that is displayed what the ComboBox is open shows
all items as blank.

We also noticed that a simple operation like MessageBox.Show("Hello World",
"My Application") renders the "OK" as blank also (no text is displayed) and
the Text property for the message being displayed (Hello World) is also blank.

Is there any issue reported with the System.String class and the XP SP2?

Any idea will be appreciated.

Thank you in advance.

Are you using McAfee AntiVirus 8?

Problem solved, that was it. Thank you much for the information.

We just disabled Buffer Overrun Protection on VirusScan version 8
