Someone mention "Mod"?
*poof
Seriously, though: Do you have extensions like AdBlockPlus or Ghostery running? If so except WinCustomize from your AdBlockPlus, and uninstall Ghostery.
I'm not running any of those programs, Doc.
When I say "Mod" btw I'm talking about the "technical, does programming work on the site", kind of Mod.
Unless of course you are that kind of Mod, in which case, thanks for showing up, Doc

Make sure you're using this version: http://www.iespell.com/download.php
Do not highlight anything and use the tool bar button.
Yep, I'm using the current version. Using the tool bar though did the trick, the option shows up there as normal. Can't believe I didn't think to check that..LoL, duh. Thanks, Yrag, good looking out bro.
I'm still interested in knowing what exactly was changed that stopped it from working in the right-click context menu on here, as it only does it here. Now in these reply boxes here the only options I get are:
Cut
Copy
Paste
Insert/edit link
Unlink
Insert/edit image
Alignment
Even those only show up when I have something highlighted. When I don't have anything highlighted I only have Cut, Copy, Paste, Insert/edit image, and Alignment.
