Yes, and because of this burn is including the appropriate CABS. Are you using 
the existing WiX build events to sign the MSI and CABS?  I do believe the 
events are timed such that MSBuild isn't going to trigger a rebuild if CAB 
caching is enabled for the project.

The checksum of the cabs before signing are the same but after signing they 
become different.
Could this be because we are including the timestamps in the signature using a 
timestamp server and as they get signed at slightly different times(in the 
build process) the timestamps and as a result signatures differ?
