I get this problem about once to twice a day while editing in netbeans. I will be editing some code in Netbeans and I get a hard freeze requiring a full reboot.

There hasn't been any correlation with an actual event that I can tell. Sometimes it's when I focus, sometimes while typing, sometimes while clicking on another window.

I need to figure out how to track down what's causing the problem, as no error is generated when this happens. No error in Netbeans logs or Windows logs. I've also tried letting it sit to see if it recovers, and it's definitely stuck.

I haven't had any problems with other apps running JRE, so I'm thinking it's Netbeans itself. I can't submit a bug report because I can't get a log or any reproduce-able explanation of the problem.
