After a system software update yesterday, the Java version on my machine was upgraded from 1.6.0_45 to 1.6.0_51. The Matlab Desktop GUI no longer works. The Matlab window does appear, but does not allow keyboard or mouse input. The terminal version of Matlab ('matlab -nodesktop') still works fine. Can The Mathworks provide a patch to resolve this issue please?
MathWorks is aware of this issue and is looking into it. Here are two other posts that are related.
I found a workaround: 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.
