opening drawing 1 vacuum together with dwg files

[gerardo25]

Hello everyone, since this morning autocad 2011 makes me a strange thing, opening a work file in dwg at the same time opens me a vuto drawing file.
the work dwg file opens properly, but I don't understand why you open that blank file too.
It never happened to me.
I uninstalled and reinstalled but nothing.
I noticed that if I click on my dwg file (or any other dwg) with the right button open with, known autocad dwg launcher, even selecting autocad2011 as the main application remains active that launcher.

autocad 2011
windows 7 sp1

If you need more information, I will be happy to provide you.
Thank you.

I solved!
practically if you right click on a dwg->apri file with, you will notice two applications the first autocad and the second autocad dwg launcher, default sta autocad, well select autocad dwg launcher.
so at opening any dwg file you will not open two files (empty drawing and your personal file).
This thing showed up after installing lumion.
to my colleague after installing furniturecad, so I presume understood by installing programs that also manage the dwg format.
as not said.
Say hi.
