Known problems

 * There is a problem with the Opera browser. GeoGebra shows the default application surface instead of the GGB file. Maybe the problem is related to security settings. Please inform me, if you are using Opera, and the error occurs.


 * There is a problem retrieving the URL of a GGB file uploaded to the MediaWiki file repository. This concerns only one installation of the GeoGebra extension; the others work fine. Maybe this is an interference with another extension.
