Project GUID keeps changing

Question

We have a VS2008 solution and i\'ve noticed something weird happening:

some projects refer other projects that are defined in the same solution (added as project ref

Answer 1

Regarding the workaround: the GUID may be referenced several places in the solution file (.sln). Remember to replace all references to this GUID, not just the one mentioned in the workaround (workaround is locked - unable to leave a comment there, so I had to answer this post instead).
