"Server Busy" and very slow after clean install of 5.0 in Bootcamp

A clean single install and validation in Windows 7 Pro and Bootcamp went fine but Rhino is very slow loading and then returns “Server Busy”. On ‘Retry’ it wakes up but very slowly and is sometimes ‘Unresponsive’ while trying to work. This is an upgrade to the latest Macbook Pro from my older one (64 bit) which never had this problem.

Many thanks,

Bo Gehring

Hi Bo- are you running plain Rhino or are there non-default plug-ins loading as well?


Hi Pascal,

Plain Rhino.



I’m getting the same issue with Windows 10 using Rhino 5 (x86) - it never use to be such, i had a few month hiatus from Rhino -
