Thanks Josef. I have had no problems rendering this example on an i7 with 8 threads in Win 7 64bit at that size, and usually have lots of other programs open too. The threads for rendering have idle priority so don't affect other programs. In fact this is the first I've heard of freezes during rendering.
There are only a few causes for programs freezing. One is infinite loops and another is deadlocked threads, and I'm pretty sure neither of those is happening in Jux. The other is the UI timing out on handling a message, which is the cause of freezes in the main window. I've done a lot of work to resolve that. But the mystery is why only some machines are affected while others have never had a freeze no matter how hard the UI is pushed - it doesn't seem to be related to Windows version or CPU or other hardware specs that I can see. I've never had a freeze on a P4, i5 or i7, which makes it hard to test directly. Debug reporting only confirms the type of freeze in this case. I'll have to take another look and see what else I can do.
For rendering, the only UI activity is once per second updates of the picture, or less often if you have zoomed out, so that should not have any chance of freezing. You could try reducing the number of render threads by one (in the More Options button beside the anti-alias control) and see if that helps.
