hi devs,
after 'bang'->[openpanel] is clicked, tcl complains about an invalid command name "e". Same with 'read'/'write'->[funbuff] of course.
Being neither a tcl/tk fan, nor an expert, I have not investigated this other than checking that sending the message _after_ itemconfiguring the message box helps. What is really going on inside is beyond my understanding.
I get this in linux with tcl/tk8.3.
