Using the GTK+ Skin, once JPasswords times out and minimizes, trying to access it again causes the security password check pop-up box to appear, but the pop-up box is blank (no text at all). Sometimes I can simply click on it and type my password (blindly) and JPasswords will open and sometimes it will not.
I have not experienced this behavior in the Metal skin.
