my enX3 no "compresses library" function!

endnote X3, word 2007, windows XP, installed times, no “compresses library” function, why?

I guess it is a bug in X3

Thomson Reuters members are probably reading?

Yes - it seems this is a bug isolated to some versions of 64 bit Windows Vista. We are working on this and hope to include this in the free Fall update patch.
