Based on the Multiflow example code
https://github.com/ShinobiControls/essentials-multiflow
My code works fine in an older version of ShinobiEssentials (2.5.1 I think) but once I upgraded to the latest 2.7.0 version I get crashes. Its seems others experience this too http://www.shinobicontrols.com/forum/shinobicontrols/2013/9/flow-layout-drag-view-from-one-container-to-another- but I felt this warranted a new ticket as this is may be a bug rather than a 'how to' request.
Basically, dragging a managed view from one flow to another, as it crosses into the bounds of another flow, the app crashes. This is not consistantly happening but for me normally within 10 moves.
Looking at the number I guess a numeric rollover is occuring but without the source code its hard to know why.
