Cannot type or edit in MATLAB, only right click and menus.

Strange occurrence today, I started MATLAB and I cannot get any input except right click menus. Running 2012a on MAC 10.6. Worked fine last night. Have restarted the computer several times. When I click on the M editor or command window nothing happens, as if it is locked up. Every now and then it seems to work for an instant and whatever inputs I've tried show up on screen, then it freezes. If I double-click a word I can highlight it, but there's no cursor function.
A few times I've gotten the following error:
java.awt.IllegalComponentStateException: component must be showing on the screen to determine its location

Any ideas? Should I reinstall?
Thanks Mark

Luke, the behavior in this question is Mac specific. Please contact Technical Support.

For the cases where the problem affects only the App Designer and such, please see this thread:

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.

Let me bump this - I still get this error on Matlab 2018a. It happens consistently when using Screen Sharing, and makes this a bit rough.
