[p4-feedback] Nimbus Look'n Feel Makes Protege 4 Beta crash on Linux

Hi Nick;
Thank you for replying, but it didn't work. I appended your line into run.sh but the error remained. Seems like it ignores LAF parameters, as I still see nimbus style scrollers around the error window.

Hi Abdullah,

You can set the look and feel in the command line (edit the script you use to start p4).
add the following:
-Dswing.defaultlaf=javax.swing.plaf.metal.MetalLookAndFeelOnce you've successfully started p4, change the default L&F in the Window menu to something that works and close protege.

You can get rid of the command line addition now.

Nick

Hello;
I'm new to protege. I've recently downloaded protege 4 to my pc on which I run Pardus Linux 2008.2.
Everything was going well until I changed the look'n feel of protege to Nimbus (I still don't know why I needed to do that?!). Actually nothing happened right away when I selected Nimbus, but then I closed Protege and, after a while, I tried to re-open it and it didn't work, prompting me a large error message. I tried to uninstall protege using the uninstaller and then reinstall, but that didn't spare me the error message too.


Here is what I do:
I follow the path to where Protege 4 is installed, and type "./Protege"
"Welcome to protege" screen appears. Then I want to open an ontology (a new one, an existing one, from the Tones repository... it doesn't matter) and the error message something like below appears:


ERROR:

Now, I would like to know if anybody else had seen this problem and if there is any solution. Any help is appreciated.
