I have a VM for a project that's gone through several versions of Workstation and (now) Fusion. The project requires a serial port, and when I converted the VM to the latest virtual hardware, the serial port setting was lost in the conversion. I added a new serial device and it works fine.
The annoyance is that very time the VM starts it asks if I want to append or replace the file. Is there a way to set a default for this? It's not a huge deal right now, but it is irksome.
