Hi Michael,
I have removed all the comment tags but still the same.
I will try installing a fresh copy of the node editor and retry editing without comment tags.
Thanks
Barry
Michael,
sorted it there was an old core file from a previous version of node editor still in the ui directory.
Removing that as cured the issue. Bad house keeping by me sorry about that.
I have a much more useable node editor ui now.
So again many thanks
Barry.
