I have had TurboCAD crash 5 times now, even after restarting my PC, when I perform the following action
1) Open TurboCAD and create NEW drawing
2) Select the SW view from the docked view menu (This step not necessary as happens in normal plan view also)
3) Select the BOX tool from the docked 3D tools menu
4) Click in the work area.
5) Enter 10 [Tab] 10 [Tab] 10 [Enter]. The application crashes
