Expands entire solution treeview on build

The solution has Qt and non-Qt projects.
Every Solution build cause the entire expands of the solution treeview (for Qt Projects).
Every single File compile cause the solution treeview to expands up to the File.
Expand is occurring at the end of the build/file compile.

Qt 4.5.3, 4.6.3 and 4.7.0 are installed, add-in is set for every Qt project to use $(DefaultQtVersion) = 4.5.3

Qt projects of the solution were created with vs-addin 1.1.5.
Migration to 1.1.6 was done after 1.1.5 uninstall.
