I am having issues with the debugger locking PhpEd. I can't figure out the circumstance that causes the issue.
My general scenario is that I am using DebugBreak in my code to debug some Ajax behavior. After I look around at issue, I try to stop the debugger and the IDE is totally frozen. I have to go to task manager and kill PhpEd. I have seen this a dozen or so times since upgrading yesterday.

Anyone else seeing this behavior?

this is expected behaviour and discussed multiple times on this forum.

Do not run synchroonus Ajax calls with embedded browser or you'll get deadlock.

Either make sure the call is asynchronous (fetches the results after-while), or use external brower. In latter case only browser will lockup.
