Comment:
sry. this was not **the** solution. after a reboot, everything was like before. again trial/error. 

"result" (?): this syntax in `.xresources`:
```
*.keysym.Control-c: eval:selection_to_clipboard
*.keysym.Control-v: eval:paste_clipboard
```

doesn't work consistently anymore since the last update.

```
URxvt.keysym.Control-c: eval:selection_to_clipboard
URxvt.keysym.Control-v: eval:paste_clipboard
```
is working - even after another reboot. strange behavior.
