The [edit this reference] button does not appear for raw references

[GoogleCodeExporter]

What steps will reproduce the problem?
1. just click on a reference in the ProveIt box.
2. Not all references will have the [edit this reference] 

What is the expected output? What do you see instead?
I expected to see the [edit this reference] button.  I see it for very few 
references, not all of them.

What version of the product are you using? On what operating system?
I guess the latest version of proveit, on Windows XP, SP3.  Firefox 3.6.13 and 
IE 8.0.6001.18702.

Hmmmm, I guess these are RAW references, and proveit does nt support them.
