Matlab desktop class failure

I am running Matlab R2012b on my Mac OSX 10.6.8. I have Java 1.6.0_65-b14-462-10M4609.

When I try to open Matlab, the icon will appear in my dock for a few seconds and quickly go away.

I CAN open nodesktop version of my Matlab through X11 without any problem. But when I try to open desktop version, it gives me the following error:

Fatal Error on startup: Internal Error: Failure occurs during desktop startup. Details: Failure loading desktop class.

Thank you

Sounds like it could be a preferences issue. Run the attached function in nodesktop mode to refresh the preferences.

Can you teach me exactly what to do? I am not really familiar with navigating in nodesktop mode, and I am not sure exactly where to tweak in preferences

Thanks again

Oh wait, didn't see the attached code... trying it now

I get the following errors running the code:

Error using figure Error using figure UIJ_AreThereWindowShowsPending - timeout waiting for window to show up

Error in dialog (line 88) hDialog = figure('ButtonDownFcn' ,btndown , ...

Error in msgbox (line 214) figureHandle=dialog( ...

Error in errordlg (line 53) handle = msgbox(ErrorStringCell,DlgName,'error',Replace);

Error in moveprefdir (line 45) errordlg(msg,'Move Failed','modal');

I am also getting these errors when starting Matlab in nodesktop mode:

Unable to initialize com.mathworks.mlwidgets.html.HTMLPrefs Unable to initialize com.mathworks.mwswing.MJStartup Unable to initialize com.mathworks.toolstrip.plaf.TSLookAndFeel

To get started, type one of these: helpwin, helpdesk, or demo. For product information, visit www.mathworks.com.
