How to delete items (specifically walls...)

[jcoles]

I had the same problem with not being able to delete or undo anything. As a newbie, those are heavily-used functions.

Thanks Puybaret, but why does the defective JNLP version remain on the Download page? It makes the product look bad.

The JNLP version works correctly for most people
It's a problem that happens under Ubuntu with Java 7 or 8. If you use Java 6 like in the installer, it will work.

Hi! I could solve this. Problem was, that the wall I wanted to delete, was hided. Unhide the wall and you can delete it. Agnes
