BCI2000 and Tobii Gazeviewer

[jeh4v]

I'm attempting to use my customized version of BCI2000 with the Tobii Gazeviewer program and the Tobii PCEye Mini camera. The Gazeviewer program captures video overlaying the eyegaze locations on the screen the user is watching. For some reason, when I look at that video, I can see the timing visualization windows and the applog window, but I can't see the actually BCI application window. I've noticed that the P3Speller window seems to have different properties than other windows (such as no title bar for re-positioning). Is there something about that window that would make it invisible to the Gazeviewer program?
