From the ADO.NET team blog Oracle client to be deprecated in .Net 4.

I must say I can understand why. When I was doing Oracle I usually used the Oracle Data Provider for .Net (ODP.NET). It was more up to date and supported more of Oracles advance features.

Hopefully this will give Oracle a bit of a kick to get them to release new versions of ODP.NET when new versions of .Net are released, instead of 6 months after a new release has come out.

I just wasted an afternoon with this bug.  In my case if the div was the first on the page the background images didn’t show.  If you inserted another div with the same styles the first div would be messed up, but the second would be fine.  Below is the fix.
