Hi Kirk,
Still using PM 4.5.4 on a WinXP SP3 PC, PM just crashed while using the structured keyword dialogue.
I wanted to report this via e-mail (even version 4.5.4 is probably not of interest to you any longer), but hit the wrong button (well, that's my fingers being faster than my brain).
Anyway, while I run PM 4.5.4 (which is also displayed during PM start-up and in the "About" window), in the crash report it indicated that I run PM version 4.5.3.2.
So, which version do I actually have?
