- When I click on another session, I'm asked if I want to save the session.
- When I click on the project- or folder-register, the changes are saved without asking.
edit: I have to correct the description of the second case: Changes in session are not saved. The session stays changed as long as I only switch the registers - but if I switch to another session and then switch back to the changed session it isn't changed anymore. This behavior is even worse, I think, as you normally don't recognize that your changes are lost.
