Controls config over-write to default - CH related?

I recently installed the new CH update for Vista on my machine.Ever since then, if I open FSX and DON'T start a flight, the configuration file (standard.xml) reverts to the "default" settings. As long as I start a flight and actually leave the airport the file remains untouched - but if I simply open the simulator and start a flight without leaving the airport (usually when checking a new AFCAD), the configuration file reverts. It does this when FSX is CLOSING.Unfortunately, I do not know for certain if the new CH software has anything to do with this - but I do not remember noticing this happening before it was installed.This happens whether it is a default flight or add-on.Only workaround thus far is to keep an extra copy of standard.xml and put it back in the folder whenever it gets overwritten.Details: AMD dual-core 64x 5400; Vista Home Premium; FSX with SP1; 4 GB memory; 200 GB HD; ATI Radeon X1650.Brian
