SOURCE Hi,

i'd like to propose/submit a patch for Dialogbox.pm

Reason:

a) If� using the DialogBox for low-prio infos in an application where there are a lot of d
ifferent parallel open windows,
user sometimes shuffled the normal DBox somewhere in the background and since they did not c
lose the box correctly the app seems to hang

b) If the App shall show some transient information (which is only a short time relevant) an
d a Dialogbox shall be shown to draw users interest

Function:
The attached patch for the DialogBox will make it either wait for the user to press any of t
he available buttons as before or after reaching an optional timeout-time the box will silen
tly withdraw by simulating a pressed default button.

Please feel free to apply this patch into the current Tk svn repository or let me have some 
feedback.

Regards,
Michael Krause.
