I have recently run into an issue with ArchiCAD 17 crashing in two different scenarios.
The first; when attempting to place an external image into an existing project. The program crashes and quits, then opening the bug-manager. When the project is re-opened and the same image is tried once again the program again crashes, then opening the bug-manager once again.
The second; when closing/quitting ArchiCAD the program crashes and quits, then opening the bug manager.
