My PhpEd installation works very well. I use debugging with 3d party server (php 5.2.1) and it is ok.
When i start the profiler, clicking on the IE toolbar, it show the error message:

-------------
Fatal error: Using $this when not in object context in dbg_eval() on line 1

Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started at dbg_eval():1) in D:\xampp\htdocs\nc\controller.php on line 316
-------------

Any idea?

I'd recommend to remove all entries referring to $this from Watches window.

Now it's ok.
Thank you.
