Hello!
Have anybody besides me noticed in pmail ver 4.70 (build 546) some oddity: when selecting a bunch of emails in a folder view ("shift + mouse click" or "ctrl + click") and after such selection by further pressing "open" or "move"- sometimes all the mails are opened in separate window (as expected) but sometimes this opening operation is performed only for couple of first selected mails intead of all selected.
I haven't figured out what influences this intermittent behavior but it seems to me as some kind of bug.
