Description John Arthorne CLA 2010-06-07 11:19:53 EDT 
4.0 SDK I20100602-2136

I double-clicked on a file in the package explorer (splash.bmp), and got this error.

Errors on console

I found these errors on my console that occurred around the same time as this NPE. The errors near the bottom about instantiating CompatibilityEditor seem possibly related.
Comment 2 Remy Suen CLA 2010-06-07 13:15:46 EDT 
Embedded editors weren't being created properly. This has been corrected.
