Basically, when I use an event between two other events, a crash occurs in a different place than when I don't.
This bug has been bothering me for a while, and only occurs on Windows 7 (Vista I'm not sure of).
See the following picture of the events...
...and the following video of what happens when event 15 is removed or retained...
What is key here is the last line of the log (list object). The event 15 makes the program crash on one line, and removing it crashes it on another line. While the event 15 is retained, the program continues to the first line of 17, whereas when it is removed, it halts before 16.
This bug is incredibly annoying by being hard to describe and hard to isolate, and I would appreciate a solution. The MFA is an secure updater and so cannot be distributed, so I will send it solely to people I trust rather than providing a public link.
