Clipboard size

Hello, I am having a lot of fun with Sculpt, but I do wonder something about copy/paste. Whenever I copy a large portion of text, a subsequent paste only gives the first part. This is most noticeable within a VM, but I wonder, since the VM can move the clipboard to/from Sculpt, if a Sculpt clipboard size limit is coming into play? If so, can the clipboard be made bigger? Failing that, can I disable clipboard integration with the VM? Apologies if this was settled a long time ago.

Regards, Colin
