I'm using Draftsight successfuly on my laptop. The only problem arise when I connect the laptop to an external display to use extended view. In this case Draftsight simply freeze on both displays and I have no other chance to get back to other PC operations than use ctrl alt del and kill the Draftsight application. This is happening only with Draftsight, no other program has this problem (including Autocad and other CAD applications). Something strange is that this issue arise both in Windos 7 and Linux environment. Also in Linux the issue is affecting only Draftsight. This issue is a big limit to me because I'm used to work on multiple display once at my desk.

Any suggestion is welcome!!!
