These are not triggered events. There is no event that will trigger them, therefore you can't uncheck them. If you want them gone, delete them. But before you do, keep in mind that some of them are used in actual triggered scripts.
If they're not triggered then which triggered ones use them. I hate hearing the swapout, purchase, and sale checks wherever I dock, and listening to half a dozen or more galnet articles whenever I fire it up stops me doing anything else because the VA commands would crash the galnet reading.
Any idea on the second issue?
