"server side php debugger" & "client side javascript debugger" can not work simultaneously.

In my "roject property" > "debug" dialog, if I click above two selection together then during the debug 
initialization, my NB ide always stopped at the browser screen, "NB javascript debugger launching. please wait ...".
No matter how long I wait, it just can not start the debugging process normally.



Background info:

if I only choose one debugging of selection, either PHP or Javascript, then the debugger works correct. which means 
both the Javascript debugger of IE or Firefox can work without problem. But the two debugger can not work together 
under the selection of "server side PHP with client side Javascript in the selectedc browser". From your UI design and 
my google results, I believe that they can work together in most people's PC. So I think mine condition is a bug.

Mine OS is WinXP of traditional Chinese.
CPU: AMD athlon 5050e
RAM: 4G
HDD: 500G
the NB v6.7 is standard edition, plugin C/C++, PHP & jMaki.


I have tested NB in another PC and the result phenomenon is the same,
OS: WinXP of traditional Chinese.
CPU: AMD athlon 1600+
RAM: 512M
HDD: 160G
the NB v6.7 here is standard edition plus PHP & jMaki plugins.


Thnks for this great and free tool,

best regard,
