@christian-knuell I am using the latest Estlcam 13.002A. When trying to hold shift/right click to drag and select the drawing so I can rotate it, half way across the drawing it just locks up, I get a white boarder around the screen. Part of the file is selected but not all of it. The drag box is still visible as well.
If I click on the screen after this everything goes back to normal and I can shift/right click and drag across the rest of the holes not selected. Just wanted to make you aware of this issue.
