PMs when minimised open new dialog button even from same user


Since i updated to the latest build, I've noticed that whenever slsk is minimised (maybe only to system tray??) that multiple private messages from the same user show a new chat-dialog button per message, rather than per user. It's on the windows build that i've seen it.

Link is to an image that will explain a lot better than me!

Seems to happen with any user.
