PS2 = is printed multiple times during the resize.  When entered is = pressed after the resize, multiple ^L s are displayed.  I set = PS2=3D"" and the brackets are omitted, however ^L still remain after = pressing enter.

Is this a known issue?  I have CC'd KSH list in case the = problem is on the ksh93 side.

Thanks
