I just had a new email, with imbedded images, open. The Windows icon changed to a smaill circle and the program closed. It is now checking through the internal files, which are 1.5GB in size. Potentially, this could take 6 to 8 hours before the program becomes active, which was needed yesterday after a power cut when it was active.
This crash with an embedded image happens quite often and seems to be getting worse.
UPDATE - It took about 30 minutes to restart in the end.
