This could take days and of course always happens when I have the least time available to investigate and am forced to kill it and delete the dsk to make it go away.
I can't help thinking that there is a clue in the fact that the deletion of the project .dsk file cures the problem. There must be something in there that causes Delphi to recreate the combination of conditions that result in the freeze. I've never looked in detail and have always thought it was just used to remember what was open, where it was, etc etc but a quick peek suggests there's a little more to it than that. Perhaps if I edit it rather than deleting it I can narrow it down. All I need is a few spare days with nothing better to do......
