Hi All,
Thanks for the replies guys.
Mac, I have Vst/DXi ticked and at the moment it is using Cakewalk' TT1 but it is the same when the Roland VST is selected. No tick in the Route midi through box.

Andrew, I thought I had the latest Windows drivers for my ATI Graphics card when updating Windows but I will double check and let you know.

I guess it does point to graphics although no other software I use has a problem and no problem with 9.5 although it does not do 2 of the things that 2010 updates allow.

I'll also have a good look through the settings Jazzman - cheers.

Thanks. Jeff
