On my computer Geogebra-Applets don't work correctly anymore (freeze or stop). I've tried all geogebra and java-Versions. JAVA-Console (no matter what version) says:

Java Plug-in 1.6.0_15

Verwendung der JRE-Version 1.6.0_15-b03 Java HotSpot(TM) Client VM

Home-Verzeichnis des Benutzers = C:\Dokumente und Einstellungen\R2-Lehrer.KATING

Bild geladen: jar:http://www.geogebra.org/web...

GeoGebra 3.2.30.0, September 22, 2009, Java 1.6.0_15

Fonts used: sans: SansSerif.plain, serif: Serif.plain

Exception in thread "AWT-EventQueue-2" java.lang.NoClassDefFoundError: geogebra/gui/hoteqn/a

at geogebra.b.w.a(Unknown Source)

....

Who knows the problem? Urgent! Thank you!

Your geogebra_gui.jar file is corrupt.

javaws -viewer

and uninstall GeoGebra, then reinstall.

Sorry. Deletion cache and new installation doesn't help. Working offline with *.jar files is o.k. But using webstart or dynamic worksheets from the Geogebra-Wiki fails. I've deactivated Virus-Scanner and Firewalls -> doesn't help (other computers with same network-configuration work well.)

Something with getting geogebra_gui.jar file must be wrong.

Strange thing. I think, I have to buy a new computer :laughing:
