[X4U] Opened for the first time?

[Michael Rath]

Lately my iMac, OS 10.3.7, has been telling me that I have been opening 
a program for the first time, when in actuality I have opened it many 
times in the past. This happens most often with the Microsoft products 
but has also happened with several other programs.

It is irritating. Is there something I did that set this off or maybe 
something I haven't done to stop it?

TIA

Mike
