I'm seeing strange behaviour with .stp files.  It seems to be some weird cache issue, where if I've opened a file, call it x.stp, and then the next day, try and open another file, call it y.stp, Solidworks always opens x.stp.  It's never the same file, it just always seems to be whatever was opened last the previous workday, is opened.  Is anyone else seeing this behaviour?  Is this a setting I'm missing?
