I see. Now I am having some similar problems with 2.8.3-rc1 and
reloads. I did not notice that until today. After I change my
CMakeList.txt  in a subproject (not sure about the root project) and
click build in visual studio 2008 I am no longer getting prompted for
the reload but the build appears to never finish. I have to hit cancel
on the build then windows prompts me to reload the project. No dialog
appeared.
