Hi again mixture! I uninstalled OE years and years ago, long before having Revo at my disposal. Revo would have got it all first time. I say that I can't remember but I'm pretty sure that it was using Control Panel because I would have had no other choice in those days.
Its removal has caused me absolutely no problems whatsoever over several years so I'm confident that I did nothing that I shouldn't have. It's just that uninstalling via CP (and I believe that CrapCleaner would have used the same tool) wasn't complete whereas Revo would have been.
It's only very recently (a month?) that this little compacting message has begun to appear (the same, unfortunately, with Thunderbird's similar-ish message) and it's only this which has made me aware that there must be a tiny wee bit left somewhere.
What do you think about my idea of reinstalling OE in the hope that Revo will be able to get hold of the program to follow through and eliminate the whole shooting match, including the historical leftover bit?
