Using PM 4.4.3, Windows XP SP2.
I cant get the IPTC Info panel, when I use the "i" key (keyboard or thumbnail icon), an error message appears : "An unsupported operation was attempted". It happens always, regardless the image format, and wether the image have previous embedded IPTC info or not.
But... I can use the IPTC Stationary pad, and it works !!. ¿?
*Edited to modify PM version. It is 4.4.3 the version I'm testing now...someone must have updated the trial while I was out. Sorry for any inconveniences.
