"I occasionally get a problem with no panel showing in the 2D cockpit. Sometimes I can cycle through the various views and when I get back to 2D cockpit mode I can see the panel. Sometimes it refuses to show or just briefly flashes up before disappearing. I have tried changing aricraft but it results in the same issue.

The dark area is where the 2D panel should be. It makes flying very difficult to do without it."
I get this problem too, it happens with any addon aircraft using the default FSX 2D panels at airports.
Does anyone else get this? Can it be fixed?
