(UPDATE - This first post has now been superseded by information further on in the discussion. Recent microsoft updates to internet explorer 11 have caused an issue with mfp that crashes it when it starts to load markets from the market locator. Other people have reported other issues, but so far this problem is the only one that has a solution identified, which is to roll back the installation of these updates)
Hi Everyone
I'm just posting this for information purposes, in case anybody has the same problem and stumbles across this thread.
After the most recent windows update in early September (windows 7 64bit), MFP started crashing sometimes on loading markets. It wasn't every time, and often simply restarting it would solve the issue, but sometimes I had to reboot the computer to get things sorted and it was a real pain.
After lots of experimenting with reinstalls, new profiles and new market locators, none of which solved the problem, I found the solution. I ran sfc /scannow from a command prompt which is a low level system file checker (search for it and you'll find instructions how to run it) This scan found some corrupted sysytem dll files, which it repaired. Since then MFP has behaved impeccably.
Hope that helps anyone who has a similar issue in the future.
