Using the latest xvile but I don't believe the version makes a difference. I know there is data in the clipboard.
If issue :paste-from-clibpard it works as expected. Per the help doc. The register name '.' contains the current selected text in xvile. Also in xvile, the register name ';' is a synonym for the clipboard. Other versions of vile permit use of '.' and ';' as supplemental register storage. However when data is in the clipboard and I do ";p I receive 'nothing in register ;]'. Wayne
