In a later session, the NAS device was disconnected and i tried to send another mail with attachment. I clicked on "Anhang -> Datei(en) als Anhang einfügen" again. Actual results: TB became unresponsive. Expected results: The Select a File window should have been opened. In "prefs.js" the path to the NAS device was inserted ("mail.compose.attach.dis", ...). Appearently TB tried to open this path and hanged. This error condition should be trapped, i think.
How long do you waited ? The timeout depends on windows and can be long (2min)
(In reply to Matthias Versen (Matti) from comment #1) > How long do you waited ? The timeout depends on windows and can be long > (2min) Matthias, tried it again. The Select a File Window was opened 105 seconds after clicking. During this time TB was dead; no "Wait Please" or "Waiting for ..." appeared.
