Thanks, tru_tru. It would appear that VirtualBox have had this bug open for at least 19 months - so if they had spent more time trying to fix this, rather than arguing over the semantics of whether experimental features should receive any support at all, they might have had a fix in by now.tru_tru wrote:For the record the summary was posted at: https://forums.virtualbox.org/viewtopic.php?f=3&t=87077
and there is an open bug entry at https://www.virtualbox.org/ticket/15835
Thanks everyone
In any case, at least there are some decent workarounds for this - thanks, everyone.
