Magento

I wanted to create a sandbox version of my existing system.  So, I copied the files to another directory, and built a new database for it.

The whole website seems to work fine in the sandbox, except when I install a new theme from Magento Connect.
It installs in the other directory, and I can’t use it in my sandbox.

Any ideas where there maybe a configuration of where to install the extensions/themes ??

Thanks !
