Thanks for your reply Tracy, no i currently am not using renders in the grid just a simple two column grid which has a value changed upon button click and I'm not using Vbox just absolute layout.
the reason i dont care about undo is that the user can change the value back by just clicking the button again. i dont see anything that might throw off the grid but i'm going to try to just put the grid into its own canvas and test it with only a few items instead of this entire application. --- In flexcoders@yahoogroups.com, "Tracy Spratt" <tspr...@...> wrote: > > That is not normal behavior.
