also , the text on the class action bar buttons is overwhelming the icons themselves , but I see nowhere that I can change the font size for that bar specifically.

For the former, I'm not sure what may be causing that one.
For the latter, Masque. I may look at implementing some per bar type options for hokey displays in the future.

Ok , getting this in combat now all the time. I got rid of Masque/Buttonfacade

Are you getting the error with just Dominos enabled?

I hadn't tried it with everything else disabled, no . I'll give it a try and if it doesn't happen , I'll re-enable addons until I find out what is causing the conflict.

Ok , disabled everything except Dominos and Bugsack. No errors.
Reloaded everything one module at a time ( I have 65 some addons installed , with all modules about 120 some reloadui's ) ...... and now it won't throw the error . If it starts doing it again , I'll try disabling addons one at a time until it stops.

Odd thing though..... during that whole process , at one point I started getting error claiming Blizzard_Petjournal was throwing a LUA error...... but once I loaded the last addon and did a reloadui...... it stopped too.
