Entering """ or '''' crashes the sandbox

This doesn't sound good. Could we get some more information about the issue? It sounds a bit more important than low priority.

Yes, absolutely:

The reason I specified low priority is it's been a known issue with userware (https://github.com/alces-software/userware/issues/22) for quite some time. What do you want to do about it?

[WilliamMcCumstie]

Hmmm this looks like a click issue and quite possible is out of our control. The bug is occurring within library code before we get to the commands. Therefore we won't have an opportunity to parse the input before it errors.

The best we could possible do is catch the exception inside the adminware command. Then possible check argv if it is running in sandbox mode, and restart the appliance.
