tcl/tk different on linux and cygwin?

Hello,
here i have a small program, which works well under cygwin, but wont under linux
--snip
#!/bin/sh
# \
exec wish "$0" "$@"

bind . <Destroy> {
tk_messageBox -type yesno -title {Does it work?} -message {Do you see this window?} -icon question
}
--snap

How it should work: When i push the close button in the upper-right-corner of the window, a message box should appear.
I use the actual cygwin packets under win xp and suse 9.0.
My question: Why will this code refuse to work under linux?
Or should i ask the other way round:
Is it supposed to work? When it comes to destroing the windows the application may be on the last breath and can't initiate a new window. Has it to do with windows/linux handling issues?
And is there a shure way of asking a user if he wants to save unsaved data when he clicks the close button?
Thanks in advance
Stefan

In wish you can't create any other windows after the base window of wish is destroyed.
But eg.

Code:

#!/bin/sh
# \
exec wish "$0" "$@"

bind . <Destroy> {
puts "Lallalaa.."
}

works fine.
