So I've come to a situation where it appears that the size of certain graphic objects is causing some pausing between layouts. For example:
Layout 1: normal image sizes, not very large, runs smooth
Layout 2: has larger image sizes and there is a pause/delay between the animated object in layout 2 showing visible, and the object beginning its animation sequence.
I haven't run this as an .exe, but I can see in debug that it's a matter of the new layout object taking too long to load.
