QProcess problem with windows batch file

[bood]

OK ,Ok, I give up...
I manage to find that it's not the problem of QT4, but rather the trick of M$.
When calling the CreateProcess to run a batch file, the working directory passing in does affect, and in an inexplicable way (maybe cmd.exe related). I've decided to use the absolute path instead.
So if anyone wants the answer, ask M$ for the source code of windows...:P, Seriously, if anyone knows what's going on, please tell me.

It's not a problem with MS Windows. I experience the same behaviour under Linux (using #!/bin/sh echo hello as a script). But this is definitely connected with scripts. I guess this might be a standard behaviour and has nothing to do with Qt.
