Opera 12.14 on Ubuntu 12.04 and on Windows (not sure which version yet):
while trying to edit a node with openlayers field and delete some point on the map the Delete key doesn't do anything in Opera while works in FF and Chromium.

Opera 12.16, Ubuntu 13.04

Workaround is to select the needed point and then move the mouse away from the map area. After that Del is working.
Can't imagine what is the logic behind the functions that take part in that bug on Opera side.
