Dear Sir,On my new PC I installed FSX and FS 2004.FSX, complete with PMDG 747-400X (Queen of the skies)performs correctly.However, I have encountered problems with FS2004As soon I click on "Fly Now"and the default frame i.e. the Cessna appears, the shown frame freezes after about 4 seconds,stops for 4 seconds and starts running again.This error repeats itself continuously.During the period the frame is frozen, I can't activate any of the menu's of the toolbar while the sound remains audible and the running prop is visible.PC specs:Windows XP (home ed.)Mem. 2 GB DDR2Graph. NVIDIA Geforce 6800 GTO 256 mb PCI-expressProc. AMD Athlon 64x2 Dual Core 5000+Although I have checked and excecuted several items of the recommendations mentioned in the FS2004 "trouble shooting"list, I have so far not been able to correct the failure.Could you please help me out to rectify the above problem.Thanking you in advanceH.R.Meyjes
