Topic Title

We're working on a project where the DataCAD file is over 37mB. When picking the O2Cviewer and then wanting to stop it (pick the 'x' in the top right corner), the dialog box closes, then only pressing the mouse it reappears again and begins the triangulating process over again as though it had just been started. I can keep picking the 'x' to close the window/dialog box, but it keeps re-appearing. Closing the drawing file (pick 'x' in the top right of the window) was the only way to stop O2C from reopening.

Is there another way to stop O2C once the Viewer icon has been selected? - or is there a bug with the 'x' - close button?
