Running FS9 on Vista SP2 - Gforce 9600M GT

Hi all,After 2 years of really bad performance with FSX I decided it was time to get back to FS9 so I could join the 2009 World flight event.I have a HP Pavillion dv7 with a Nvidia 9600M GT graphics card running Vista SP2 and 4 GB RAM. I updated the drivers for the video card to the latest edition (27/08/2009). Unfortunately FS9 won't behave like it is supposed to ! In 2D I can't switch between views, cockpit view works fine but pressing "S" doesn't change the view but I does change the sound effect. In full screen mode switching between views works but I can't open subpanels (e.g. press "2" to open pop-up) except when using the "Views" menu options.So far I have:- updated video drivers- deleted FS9.cfgTried all kinds of settings in the display menu.All to no avail, did anyone have this problem also and did you find a solution ?Thanks,Bj
