I also populate a field and adjust its rect from custom properties, as well as adjust some
controls based on stored custom property settings. I also load an image from an unplaced
background. So, lots of setup on preOpenCard.

The background image appears in chunks and text in the fields comes in as sequential pieces. The order of the display varies, sometimes the text appears first, sometimes the background image. The first few cards are fairly normal, but as she pages through the stack it gets slower.

She stopped when usage got to about 50% when she said it was unusable. This was in the IDE. She says the standalone is even slower.
