GMax minor issue.

I've a small but annoying issue with GMax.  When I pan in any viewport, the model vanishes and all I see is the bounding box.  When I stop panning, the models reappears.  Up until a week or so ago that didn't happen--the model never vanished while panning.  I must of changed something, but damned if I can discover what it was.  I've fiddled with the various settings to no avail.  Any help would be appreciated.

Not sure if this will work in gMax.  In 3DSMax it is a hotkey 'O'.  You can unintentionally press it and there is nothing on-screen to indicate that you have done so.  Somewhat annoying...
