I have stupidly removed all the toolbars including the menu toolbar (to mazimise screen space while viewing thumbnails) and I can't find a way to get them back - any clues please? I've been through all the Preferences and search Help and this forum.
Click the window icon (top-left of the window frame) and the menu in there has a Customize option, in case all the toolbars are turned off. You can then turn them back on on the Toolbars tab.
thanks Leo - back to normal now
