11740 Weird copy past issue

I’ve been having copy/paste issues with Touch on my office system, which don’t seem to happen on other workstations. It could be related to my keyboard, which is a wireless Logitech K800.
What is strange is that if I control-click on a param and copy it from the context menu, it gets stored to the clipboard properly and can be pasted. If I copy text from a DAT and then open an external editor, I can also paste it in there. And I can copy/paste in other apps without a problem.
However within Touch, control-c/control-v don’t work…
Any ideas why this could be happening?

Thanks
Alex

Just to make the situation weirder, I realize that I can copy/paste nodes without a problem, just not text within nodes, i.e parameter to parameter or DAT to DAT…
