failed installing nusphere solution on a xp

Hi, I become better and better in php programming. I was working with phpcoder + php 4.06, that i unstall temporary. I m looking for a powerfull editor, I found phped in screenshots of the dbg site. I cant work seriously without a debugger. I download the eval version of phped. I install the techpack + phped3 eval. I can only debug in local cgi mode, no http debug seems to work. I notice a strange thing in the php dir (only) when runnig php.exe on the command line it displays "failed loading php_dbg.dll", but every thing seems to be ok ! I make a copy of php_db.dll in ../extensions, apache make a core dump. I tried with the dbg dll that coder has, ... I get the same things: fail ... +dbg 2.04 incompatrible with zend... k I dont understand :( I install everything by default. I notice that when giving a *.php script url that deoesnt exists, the listener casts the editor and I can see somes php globals vars, like phpcoder when it was working. But nothings happen when a well and existing php script is called via the browser ?!, except if it has parse errors so the listner give hand to the editor. Have I to make some errors to take profit of the debugger ? I dont know if some could answer me here, case zend is proach of php, and zend is a concurent of nushpere for its editor, is the still a community ? Thanks for your echo.
