Hey, Kirk -
Long time no talk!
I've also run into issues with the stationary pad (SP). Sometimes, while doing copy/paste with key words in the single-line edit box, PM will just quit (not even a Dr. Watson). This is under WinXP. Other cases in which I thought I'd edited keywords, and then saved the SP to a file, the file will be missing keywords altogether. Not easy to repro, though last night, I was able to watch PM just quit (and I mean disappear instantly) 8 or 9 times.
The only things I was editing were captions and keywords, but extremely goofy. This was under version 4.5.2.
I've now upgraded to 4.5.3.1, and you'll find another post from me on that version...
Cheers, dude!
Jerry
