Spell check does not work

[ukrkoz]

Spell check/correct does not work for me at this forum. When I type, misspelled words are underscored, as usual, but when I R click on them to chose properly spelled word, it only displays "Paste" option. That's it.
Suggestions?
Windows 7 Mozilla Firefox. SO far, this is only on this site.

Firefox has a workaround for this site. Hold Ctrl when you right click.

Oh. OK. Thank you.
