Just did some testing in Ubuntu, also in VMWare Fusion in a Macbook.

Running with the "Cuis recommended" VM (as per 
https://github.com/Cuis-Smalltalk/Cuis-Smalltalk-Dev/blob/master/Documentation/GettingStarted.md 
), I see the same behavior as Nicola.

The good news is that with Gerald's VectorGraphics VM, available at 
https://www.dropbox.com/sh/rhkt4ayq24t2xbf/AACDb3mrjMUDB8Mptd-Bi6Zsa?dl=0 , 
it runs ok. Same with latest build from OpenSmalltalk: 
https://github.com/OpenSmalltalk/opensmalltalk-vm/releases/tag/latest-build 
.

So, it seems it is a bug in the Linux X64 VM, that has already been fixed.

Thanks,
