Hi,
I'm running Hurd in VirtualBox.
If I run the latest versions (gnumach-1.7-486.gz) with the reverted findutils (as per James' email),
then on scrolling the mouse a few times the system freezes with:
mouse: queue full
On rebooting and reverting to gnumach-1.6-486.gz this is not an issue.
Cheers,
adam
