OK, this is driving me insane....

I'm running v5.9.0 on Fedora which was working fine until earlier this evening when I lost the toolbar in the batch queue manager and I can't see how to get it back again. So far as I'm aware that's the only place the toolbar has disappeared from.

Can anyone help?

Thanks.

Managed to work it out by booting into my backup environment...

The batch queue manager dialogue had somehow lost both the menu bar and the toolbar. Ctrl+M got the menu bar back, from where I was able to reenable the toolbar from the settings menu.

Still no idea how I managed to hide them though!
