OAuth "Fully automatic" dialog hangs

[wernerschka]

What steps will reproduce the problem?

1. With new JOSM 9900 I was "recommeded" to use OAuth Wizard before uploading my data. So I opened the OAuth-wizard within Settings and choose method "Fully automatic". I entered name/password and clicked the Button "Now Authorize"
2. For some reason the OSM-server sent an error, Authorisation not succesful
3. Now the problem: I can't close these Wizard dialog any more. Wheter i press the "Cancel" button nor the "X" in the top right border of the dialog, nor change to "Semi-automtic" or press the "Help"-button. Seems the dialog hangs or died.

I can't change back to JOSM window to save my work or try another upload.

What to do to close/kill this dialog? I don't wanna loose hours of mapping work because of this bug! :-(

Btw: I started a second JOSM instance and tried "Fully automatic" again. Again an error, but at least I could change the drop-down list to "Semi-automatic". Using Semi-automatic I finally got the token within this second instance.

Please provide any additional information below. Attach a screenshot if possible.

From wernerschka:

I finally managed to kill the dialogue window: I started Windows-task manager, choose the "processes" tab and killed a process called somethinkg like "Desktop window manager". Then i was able to close another JOSM dialog OAuth-messagewindow and then finally could work with JOSM again.

I had exactly the same problem today with JOSM 9900 (and OS X 10.9.5). No problem with the stable version before some days ago.

Then I downloaded Build 9912 (02.03.2016 13:10:17) – josm-custom-macosx. With this version, the authorization process did work!

Worksforme with current web started JOSM. Cancel closes the dialog without problems.
