Javascript and PHP debugging problems

Hello,
yesterday I downloaded the pre-release "WebIDE - PHP developer edition" and I tried to use it on a web application.
My application has a mix of *.js and *.php files and I normally use a developing local network server. I have an apache+php (5.3.0) server running on this machine and I installed Xdebug 2.0.5, adding this section in the php.ini file :
[xdebug]
zend_extension="C:/php/ext/php_xdebug-2.0.5-5.3-vc6.dll"
xdebug.remote_enable=1
xdebug.remote_host="192.168.2.150" <<-- this is my local IP
xdebug.remote_port=9000
xdebug.remote_handler="dbgp"
xdebug.remote_mode ="req"
xdebug.remote_log="C:/inetpub/temp/Xdebug.log"
xdebug.profiler_enable=1
xdebug.profiler_output_dir="C:/inetpub/temp"

My problems are:
1) Cannot debug PHP files without stopping first on the first file (index.php) and then moving to the other included/called php files. I.e. If I only set a breakpoint on "engine.php" it doesn't stop.

2) Cannot debug Javascript at all: I tried the two Javascript Debug Configurations (remote and local), but breakpoints are simply bypassed. In the remote configuration I installed the JB Firefox plugin and also I tried to set breakpoints in a new index.html or in a *.js file, but nothing changed.

3) When I will be able to debug javascript code will it be possible to debug javascript AND php at the same time?

Thanks in advance,
Flavio
