Alejandro,

	I try something else:

#---- tcl program starts here
% proc foo { args } { puts "foo" }
% bind . "<Button-1>" foo
#----

This gives me an Error: unknown option "-state". Here is the log file

unknown option "-state"
unknown option "-state"
     while executing
"$w cget -state"
     (procedure "tk::ButtonEnter" line 3)
     invoked from within
"tk::ButtonEnter .
"
     (command bound to event)


I try searching for this on the internet and it appears as a tcl/tk 
mismatch version. As I said before I completely remove the c:\cygwin 
directory and reinstall the tcltk package.

Comments/suggestions *really* welcome

Thanks a bunch
Mathieu
