Solved
Hallo Leute,
Ich arbeite mit Mac, Geogebraversion siehe hier:
Wenn ich in der angehängen Datei die Winkel des Dreieck "Vieleck1" messe, indem ich das Winkelmesswerkzeug auswähle und dann im Algebrafenster auf Vieleck1 klicke, zeigt Geogebra komplett falsche Winkel an:
Wenn ich Geogebra schliesse und die Datei neu öffne, stimmt die Anzeige zuerst, wenn ich das Dreieck aber in der Grösse verändere, sind die Winkel plötzlich wieder falsch.
Was ist hier los?
Herzlichen Dank und freundliche Grüsse
Martin

The same problem 
As I wrote: When you close and open the file again, it works (at least it worked fine until I bound the upper point to the Thales circle, then it went wrong again)! I don't know, what the problem is, but even when I tried to reconstruct the whole thing from scratch, it happened again... Developpers?
Thanks, Martin
We had this bug (internal angles of polygon drawn outside) a couple of versions ago but it should be fixed now. Did your installation update properly to 5.0.386.0?
My version is 5.0.372.0 only but it doesn't want to update automatically. How can I clean the complete installation on a mac? Just delete the program or are there some more files (library? plist?) to delete? I've got also the problem that I can't open several files at once so I think it would be good to do a proper clean-up and re-installation...
Thanks! Martin
I removed my old version and installed 5.0.386.0 and now the error vanished. But I still got the issue that it's not possible to open several geogebra files from finder at once... But I may have to open a new thread for that. Thanks!
Regards, Martin
I think that's a known problem reported elsewhere in the forum. I'm not sure we will be able to fix that as our focus is more on Classic 6 and Graphing / Geometry apps that use geogebra.org as the primary storage of files (with possibility to save offline, of course)
