What exactly happens since the time you call "before"?

I am using 10.6.8. It worked well before and I haven't changed anything. It is so strange. All of sudden it broke and it did not help by reinstallation.

It's a java problem.

I found a workaround for 10.6.8 at least:

    Close all programs

    Go to Applications / Utilities / Java Preferences

    The Java Prefs app will open

    In the 'General' Tab, change the order of Java SE, so that the two with the older versions are on top.  The versions are in the RH column on my system.  For example, my toplisted version was 1.6.0_51..., which is the latest version updated yesterday.  There were also two entries for 1.6.0_24...  Drag these so they are on top (64-bit first)

   Close the app

   Start MATLAB.  Now I can type and everything is good.

Thanks a lot. Yes that is the problem with Java 1.6.0_51. I restored Java from my backup with the old version 1.6.0_45 and now matlab is working.
