Karl ... and apart from the limited Merits, welcome to "DLL Hell". You know, they all share a DLL but were developed with different versions. Install a new program, it "updates" the DLL and older programs (expecting the older version) break ... shouldn't happen but it does ... makes the old days seem a cinch ... you know, like on the Mac, delete a prog and it's gone... no depencencies, no registry with it's knickers in a twist ... Back to photography: remeber when people here moaned that talking f-stops was "counter creativity". Makes all this computer stuff seem a doddle really. Bob (f23) Talbot
