Use caution when downloading the Peter Witt streetcar
I'm not sure if this applies to later versions than UTC, but if it you decide to download the Peter Witt Streetcar (to UTC, not sure about later versions), please beware that when I downloaded it to UTC, UTC failed to start, and almost got corrupted. When I un-installed the streetcar, the simulator was then okay. I'm not sure if it affects later versions though.
