Thanks.  I have tried this process several times to no avail.  I still can not see gauges in the VC, but all systems seem to work correctly.  When pressing SHIFT+number keys to open the panels, they flash black quickly and then disappear.

the is the first time I've had any problem with the B707 since installing it over a year ago.  Are there any conflicts with other files or settings which I could check to resolve?
