C#: dobbel respons på eventer C#/glade/gtk/mono

[ways]

har problemer med en test jeg lager i C# under mono. bruker gtk og glade.

 

problemet er at når man klikker på en knapp, så sendes eventet to ganger. to openfile-dialoger kommer opp. hvorfor??

 

kan legge opp glade-fila også, om det hjelper noe. alt den gjør er å definere utseende, og sende Click-event på knappen.
