Hi Duane Thanks for all of your suggestions. I knew some of this and learned some more from your suggestions. I knew nothing about examine-relay so thanks! I wasn't sure whether the fact that the crash was breaking kWin would stop this logging mechanism working. I confess I haven't yet tried it ;-o . I do have Windows programming & debugging experience so that should help. Actually, since I posted this I have become advocate for this program with Codeweavers. I am guessing that the same debugging techniques will apply. Is this true, of have Codeweavers modified things in some way?
