Strange, it really must be a ghost. I can't capture it. It happens right in between the initial long rectangle "loading" box and the full screen where it says "loading airport, ect."

I did have the RF5.5 free trial , but have uninstalled it since buying the RFG6. It's not much of a problem, just a see-thru window that is about 1/4 of my screen during start up. I don't recall it being there before. Only thing I've done is imported a dozen planes from KE.
