G,day Tim,
I have  upped to a new computer  1xi7930CPU-6DDR RAM-2x1TBHDD-GrForce 480GTX PCI-E.
I installed FSX and your Plan-G(V0.9.1.423)
All worked very well till recently when error message keeps appearing.,in the Plan -G window
"Stop Running this script"
"A script on this page is causing your Web Browser to run slowly. If it continues to run, your computer might become un-responsive."
Also get an error message " You have ran out of available memory and Windows is going to shut down"
My virtual memory is set to 6144mb.
I have not installed any scenery etc addons to FSX instal.
Any help would be greatly appreciated,
Regards,
Andor.

Sounds like you have too many overlays turned on for your current zoom level and window size. The biggest culprits are 'small airports' and 'intersections', particularly in extremely densa areas such as the USA. Either turn down your settings (or click Reset All' on the Map ribbon), or if that proves troublesome because of the timeouts, run the MapReset.exe app, which will do the same thing from outside the prog.

Many thanks Tim... admit I have everything pretty well maxed out.  Will give it a go and keep you informed.

Andor
