This has been a long standing issue for me with rF2 (i.e. for years now) and it's about time that I reported it. I've never seen mention of it before, but I'm not really one to check bug reports. This is occasional and rare cannot be reproduced as far as I can see. It happens on occasion that when a track is loading, the loading bar will stall at some point and not proceed. Upon Ctrl-Alt-Del, it is revealed that there is an error dialog box open behind the loading screen similar to these: View attachment 16692 No matter what I do, there is no getting around this until my computer is shut down and restarted. Then I may not see anything similar reoccur for a month or more. When this happens, something is persistent that I cannot find but once I restart, it won't happen again. This particular incident happened after a number of times running the vmod (latest Skip Barber @ latest Lime Rock Park with the latest build).
