FSX Loading Screen on approach

Hi GuysJust got a new PC and have installed FSX with rc4, rex, and ASE. Ive also amended the FSX.cfg with Bojotes automatic tool and am using the FPS limiter set to 30FPS..Overall im really pleased with the performance of the sim but there is a recurring issue that is really starting to grate.On a number of occassions when i am on approach to land into a major airport, the screen goes black and the FSX 100% loading screen comes up, only for about a second or 2, and then the sim continues on from where it left off. |Im not sure if this is asomething to do with texture load but to be honest id rather the sim stuttered at this point, rather than stopping and restarting as it really loses the realism effect.Ive got most of the settings in FSX maxed out except for AI (very dense) and AI (50%).My PC details are: Intel I7 2600; NVIDIA 1.25Gb GTX570; 8gb RAM; 750Gb WD Caviar Black HDD.Anyrthing you can suggest would be gratefully received.ThanksDonald
