X11 application (Matlab) won't respond to any keys/mouse, grey window on minimize (Snow Leopard)

Question

Suddenly my Matlab (2012b) won't run. It starts fine but does not respond to any keys if I minimize it it comes back as just a grey window. I tried reinstalling Matlab, then xQuartz (I actually uninstalled it and installed). Any idea what can cause that?
