i had problem with my user groups not being correctly defined in the default audience setting. I created a new user setting (called ALL intead of default) but everyone in there and that seemed to fix the problem.
I got a nice response in another thread about using a .css script to autosize them.. it seems to work.
Yes yes there is a hack made by happy linux (ohwada). Haven't tried it and don't know if it is XOOPS 2.0.13.2 and/or 2.2.x compatible. For that compare the files!
