Select a folder in PowerMail Put some text in the little search (or filter) field in the upper right
Wait a second or hit return and allow the search to complete. You get the search as you should. NOW go to a different folder. Your search string will still be there, but there is no way to get it to do the search without editing the string. One would think that the search would still be active, or that putting the cursor in the search box and hitting a carriage-return would do the search. But these are not so. You have to change the search string to make it "active" again. Very un-intuitive. Perhaps the best thing would be for PM to clear the search string field when changing mailboxes.
