If I open MUI prefs, and press more, select the TextEditor, and under settings use the slider for undo levels, I get error messages from the log server popping up.
Sometimes it gives the message MUI Unknown Exception, or I get the Illegal instruction. In both cases the MUI prefs window will stop responding.
This happens often right away when I start by moving the slider quickly to the right. Other times I am able to move it right and left a few times, and sometimes even change the setting and press use or test and close the MUI window. But if I move the slider many times I always can produce this error.

Does this happen for anybody else, or is it something with my setup?
