I have a list of several dozen elements. I shift clicked the first and third element. Elements 1 through 3 are selected as expected. I shift clicked the 6th element and get elements 3 through 6 selected, with items 1 and 2 no longer selected. 

Quite annoying as you can imagine. Is there anyway around this? The elements are being selected with 

.children('.ui-selected')

Thanks! :D
