--- Comment #2 from Danny Staple danny@orionrobots.co.uk 2009-06-02 06:37:28 --- The log I have attached is based on "wine ..path-to-sketchup.exe.. 2>&1 >error.log" so all console output will be there.
I have deliberately not used winetricks as I understand defect reports after using it may not be addressed.
I will clone my wine config folders and try it though - just so then I can return to the unaltered state if that fails to work.
