[Owncloud] Beta 4.5.0 IIS 7.5 Win7x64 PHP 5.3.17

Thanks for ownCloud.

ownCloud Installing from the 4.5.0 beta zip seems rather unstable - for 
example the File app will spin constantly when an upload is attempted. 
It then looks like the server itsefl stops as no subsequent connections 
are possible.

The current release Zip installs correctly

I'd like to understand what is happening here. Is there some background 
on how to debug PHP apps in general and ownCloud in particular?

Thanks

Jerry
