tiptopgem, do you by any chance have Bitcoin pinned on the Laucher?
As soon as I unpinned mine from the sidebar launcher I got the menus back. Now at least I could change the options to close it instead of minimizing to tray lol
EDIT: Fixed it.
As soon as I unpinned it the icon never again showed up on the launcher sidebar. Here's what I did to fix all of the problems.
Open dash, type Bitcoin. Get your mouser over the Bitcoin icon and drag it to your desktop, it will create an icon/shortcut on the desktop. You can drag that shortcut to the launcher sidebar if you wish and voilá, whenever you use it, be it on the desktop or on the sidebar launcher, you will have the menus and system tray icon back
For some strange reason, when I added the desktop shortcut to the sidebar launcher, it remained there but it didn't had the little arrow that open apps have. After a couple restarts I managed to drag the Bitcoin shortcut from the dash to the launcher sidebar and now it works as intended, menus and tray icon included, having the arrow on the side od the icon when the client is open.
Some odd shit, I'll tell you that lol
