Did you install the mod by hand or with EasyMod? Also, are you using the lock/unlock addon? If so, did you install the actual lock/unlock mod?
Thanks for your response, smitjel...I did install the mod with EasyMod (one odd thing...after installing, it did not show up in my list of installed mods, although it is clearly present). I have also installed the lock/unlock mod.
And I'm guessing, in your case, the Preview button and the Submit button do the same thing? Have you tested the Preview button just to make sure you didn't swap the buttons somehow?
That's correct -- the Preview and Submit buttons do the same thing. I have tested Preview (after reading a few posts on the board regarding a similar problem) and confirmed that I didn't swap the buttons.
Searching through the board, I see that at least one other person has had the same issue with a different quick reply mod, and resolved it, but didn't reveal his solution. D'ohh!
