Hi Fergus,

I am a very very newbie!

I suggest you to exit "PROPERLY ALL APPLICATIONS"

opened ( included those you MIGTH have forgotten!!!!).

before "exiting any SESSION".

I haveencountered almost such a problem with some

older versions.

I used the "trick" completed, sometimes, with the "windows

chkdsk program" (the corresponding of"fsck program"

on the the "Fat Partition"

Good luck !
