QtNetwork.dll is not getting terminated.

[mady]

Hi experts,
I have developed an application where I am using NetworkAccessManager (NAM) to download a XML file from server. I am using get to initiate the request and waiting for NAM 's finished() signal to get called and copying data from network reply. My application is a plugin of Visual Studio2010. I am destroying object of NAM on close of VS.

Problem: Even after closing of visual studio I could see an instance of devenv.exe is still running. When I attached VS to leftover devenv.exe I could see main thread is waiting on QtNetwork.dll. Not sure why it is getting hold. How to stop QtNetowrk.dll gracefully?
I am suspecting is it because of deleteLater() I have set in reply......

Any help suggestion will be appreciated.
