On one of my upgraded Lubuntu systems (12.04 to 12.10), I had installed specifically the open Java 6 JRE/JDK (instead of the default JRE/JDK, which in 12.10, is Open Java 7). On that machine (which doesn't have Open Java 7), everything is fine - the Java applications are displayed on the taskbar. So it appears to be a problem with Open Java 7. I did still more checking on the machines that had the problem. I found that the problem (no Java applications in the taskbar) was present after the upgrade, and before any Java updates. After applying the Java updates (to both Java 7 and Java 6), the problem was still there. So the problem was not introduced by the recent Java updates. Sincerely, Aere </PRE> </BLOCKQUOTE> <PRE> All: </PRE> I have successfully worked-around this problem by removing the default-jre and default-jdk packages, along with the specific open Java 7 packages. Of course, at some point, it will cause problems for me again when I eventually have to use open Java 7. But maybe the problem will be fixed by then... - Aere <PRE> Sincerely, Aere </PRE> </BODY> </HTML>
