What I Do:
For a single jumper, I leave it out and lay the spread.
For two-three jumpers at different times (not all at once), I write them down and set them back in the spread.
For more than 3 jumpers at different times, I hold them out for positions in the spread. Draw the remaining number of cards left, and I shuffle them to figure out what position everything belongs in. (This is a little weird. I've never met anyone else who did this so far.)
For cards jumping at multiple times (two or more falling out together), I re-start entirely, center myself, and shuffle again. If multiple jumpers happen again, I put the cards away, as I am clearly too scattered to ask that question at this time.
These are just the weird things I do. I don't even entirely remember why.
