On going issue

Help! I am new to Xdesign and keep running into the same issue. I asked about 3 months ago and no one has had a solution. I'm still dealing with it so I thought Id ask again.

 Often while using Xdesign the cursor icon changes to a selection icon. Once this happens there seems to be no way to exit, I have to close the drawing and re-open it. Sometimes I can go an hour without it happening, sometimes it happens every 10 minutes or so.

Anyone know what causes it or how to exit?
