I tried to fix the problem, but it appears to be a bug in a Tk widget 
that is not maintained any more (mclistbox). At the time I integrated it 
in tcltk2, it was fully functional. At this point, there are three 
possibilities:

1) To use a Tktable widget instead (also supported by tcltk2),

2) To use the newer tablelist Tk widget, but that requires some work to 
incorporate it in tcltk2 (http://wiki.tcl.tk/5527; the best choice I think),

3) To fix the old mclistbox widget (we need a good Tcl programmer here).

If someone wants to submit a patch for #3, or work on a solution for #2, 
I will gladly include it in tcltk2.
Best,

Philippe Grosjean
