I'd say it's probably a bug in the Windows port of tk. WinSight shows
that after the dialog all mouse messages are sent to the containing
window, not to the controls. Also, the following tcl code shows the same
problem in Wish 8.0:
  button .b -text "Click here" -command {
    tk_messageBox -message "Button pressed"
  }
  pack .b
  tk_messageBox -title "Welcome" -message "Hello, bug!"

I posted a different workaround yesterday in response to a similar
question.
