I'm having the problem of spaces appearing in hierarchical/structured keywords and popping up as duplicates in Lightroom lists and elsewhere. The problem seems to be one that others have had, but I've followed up on the Forum postings about configuring the IPTC/XMP settings and so on.
The situation is that in my keyword hierarchies on import into LR3, I get *duplicates as LR3 treats the leading and trailing whitespace as significant. This *may be more of an LR3 issues — but as well, it seems to me that I should ask in the PM forum if anyone else has had this problem or a solution?
I've posted a screencast film of the situation at the link below. You can see how the PM3 assignment of a structured keyword creates two seemingly identical keyword hierarchies in LR3, which quickly becomes a mess — like having lots of *almost the same socks in a drawer.
