[vs-addin-1.1.6] strange behavior of visual studio add in with vs 2005

[typedef]

Hi,

I have Qt 4.6.3 and I just installed qt-vs-addin 1.1.6 for visual studio 2005. (I had 1.1.5 and it worked fine)
It is still working, but every time I build my solution, the add-in expand the entire treeview of the solution. in my case that means a lot of project, and a lot of virtual dir and files, and everything expanded = big mess. It does not cause any trouble for the compilation, but it's a strange annoying behavior.

Does anyone have this problem too ?
