Possible issue with 2010 SP 4.0

We use a pdf of our logo in our drawing format sheets. After installing SP 4.0 yesterday, I noticed that the pdf was no longer visible on the drawing format. This applied to both new and existing drawings. I uninstalled SP 4.0 and went back to SP 3.0 and everything seemed to be resolved. I can only assume it was an issue with the later service pack.
