Thanks for the quick reply Franceso, Unfortunately I still cannot get it back to normal. Shift + right click only hides the Windows taskbar again. Alt+spacebar+M does nothing.
I wonder if there's antoher keyboard shortcut to fix this.
Thanks anyway. Will keep trying.
EDIT: Got it!! When the TM window is maxed and the taskbar is not visible, I pressed Shift+Alt+spacebar and a menu appeared. I select Maximize and it restoreed back to normal.
