[Valley] Map editor issues: S key not working

[TMarc]

The key S does not do anything, although it is meant to save a map.
I would expect at least a quicksave if you already saved it once with a new name, but nothing happens.
Only when I click on the disk button, there is a message that the map must be validated, and then it saves.
And then there are 2~3 popups that have to be closed - but I would also like a real quick save...
