I have only activated php_mssql7.dll

The error is like:
I n the server console an eroor message pops up telling:
---------------------------
php.exe : Application error.
" Intruction "0x7800..." has referenced memory at "0x0065...". I has not been able to write to memory.

Choos Ok to end application.
Choose cancel to debug application.
----------------------------
As you can see It's very likely to be a pointer error , which i think should be corrected.

Thanks anyway
