Renumbering Bug (1618)

So I had four cues (1 thru 4). I renumbered 1 to be .5 and then I tried to renumber 2 thru 4 to be 1 thru 3, but they numbered themselves 1, 1.1, and 1.2. So then I tried to renumber 1.2 as 3 and I got a Network Error window. Nothing crashed, but I couldn't get renumbering to work right. When I hit the renumber button on the header of the cuelist window, they went back to 1 thru 4. Am I not doing this right?

Here's my syntax...
Cue 2 Thru 4, Renumber, Cue 1 Thru 3
