Paste doesn't work in Komodo 9

I’ve just started a 21-day trial of Komodo 9. Looks amazing, but there’s one fundamental problem. Paste doesn’t work, neither as control-V nor off the context menu. The copied text is available in clipboard, which I verified by pasting the copied text into Notepad. Control-X also cuts as it should. But the behavior of Paste (control-V) is not correct. If I paste over a selection of existing text, that text disappears, which seems to indicate that an empty string is pasted. However, the copied text remains available on the clipboard. I’m running Windows 7 64-bit. Is this a bug or is there a setting that I can change to fix this?

Will continue this thread on the bug tracker, no need to report this in multiple places.
