Ok, maybe I misread it. I could have sworn that I'd seen that, but all I can find in forum searches and searching the versions.txt file is that it's disabled for Wine as of 7.02. Still, I was certain I'd seen that it was disabled altogether, but I can't figure out where I saw that. Maybe I'm imagining things.
But I do know that it hasn't worked since either the first 7.x beta or one of the first. There was a change in the richedit version being used and maybe that was the cause, but from the versions.txt file, we're using the original version again, so that shouldn't be a problem now if that was the case. So I'm not sure.
