I can open FS9 and select a plane and a flight plan but when I get into the 2D cockpit or spot view I get the round blue busy cursor constantly and the simulator does not allow me to use the mouse to select or change numbers in the autopilot. I have checked the applications and services running and closed them one by one with no change. I have the most up to date certified Nvidia drivers for my video card.I have noticed other people having the same problem but do not find an answer.The following are my specsDell Precision 690 with 2.3 Ghz dual coreNvidia Quadro FX 4600 video card with Nvidia 197.90- certified driversWIN 7 64 bit Pro8 gig ram(2) SCSI 300gig hard drives.

I have now narrowed down this busy cursor. I can start FS9 in WIN7 64bit using standard FS9 aircraft. Will actually fly even with add on scenery. As soon as I change to an addon plane the busy cursor (revolving blue ring) comes on the screen and doesn't allow me to use any mouse clicks in the cockpit rendering the simulator useless. I'm not quite sure how to troubleshoot this problem since it involves only addon aircraft. I was thinking that I would attack the problem as followsdelete all addon aircraft and add one by one; if that doesn't work I will remove all addon gauges and reload one by one.If that doesn't work I will uninstall FS9 and reload (dread this step).If these steps don't work I may have to buy a copy of FSX and start all over unless someone has any better ideas.Please help

A few questions for you.Where have you installed FS9 and have you also installed the 9.1 patch ?Are you the administrator for the computer ?Have you installed the addon a/c from scratch...ie not just copied files from another computer ?The suggested way to install FS9.1 is:In it's own seperate folder in the C drive (NOT program files), or in a seperate partition.Install by right clicking and choosing "run as administrator". Same goes for the 9.1 patch and all your addons.Turn UAC off.Peter

I have followed the procedure of not putting the FS program in 'Program Files' and installed inthe C: root. System seemed to work until addon planes wer added (copied into FS directory "Aircraft' directory. Will try to delete all addons and add one at time. Stay tuned

You need to install addon planes using the installer I believe. There will be other folders than "aircraft" that will affected as well as the registry. My method when moving to a new computer/OS is to save the aircraft.cfg file and the texture folders, as well as any navdata/FMC files, and then copy these over AFTER i have run the installer for the a/c concerned.Peter

I have found the solution thanks to these formums. I removed all of my addon planes and slowly re-installed them. The same error was occuring, busy cursor and panel frozen. Whaat I discovered was I had FS Panel Studio installed and FS9 was trying to load a panel thru FS Panel Studio and could not find the required path. Unfortunely the only solution to this was to reload the original panel from original ZIP files and then modify panel.Thanks again for you help
