I added a check for this situation in 30ccd82. Can you explain more details about what you were doing when this happened? It seems like you were either hovering over a dot or recently selected one. I'd ideally like to fix the cause of this error vs just catching it when it happens.

There is currently a reset happening at the beginning of this method to ensure velocity was not incorrectly set to 0. Yet I am still getting bug reports saying velocity was set to 0 later on when an attempt was made to set the x value. I am going to update the bug reporter to include details about the version of KeepTrack that is running. It is possible that older versions are being used somewhere.

Premade missile simulations were one of the culprits. I fixed that scenario, and they may have been the only issue, but will leave the velocity check in place until I rule out other scenarios.
