Progress bar completes too soon.

From Guillaume's comment on the introductory blog post:

In the solution I'm working on at the moment, I've got several build configurations. The one I use the most usually builds only 6 projects, the other two build all 78 projects. When I build either of these two configurations, the progress bar reaches 100% way too early, suggesting that it keeps the number of projects to build from the first (?) configuration for all subsequent builds. Does it make sense?

To reproduce that problem, try unchecking the "build" checkbox for some of your projects in the build configuration manager (not sure what the exact terms are, I'm using the French version of Visual Studio), build that "partial" configuration first (as in "right after you start visual studio/load the solution"), and then build the "full" one.
