Rated 4 out of 5 stars

On TB115.7, once the extension has been activated, the [Copy Patch] button only works once. Thereafter, it remains grayed out, even when browsing other messages. To reactivate it, I have to open the extension manager and deactivate then reactivate the extension, or restart TB... Extension which is quite handy otherwise...

Ouch. I'm still on 115, so I didn't notice this behavior yet - provided it is caused by the newer TB version. I'll try to reproduce that.
