Scott -

Something to bear in mind is that large forms account not only for the big bitmaps, but also for many of the large byteArrays, since forms convert their bitmaps to compressed byteArrays when they hibernate.

One of the first things I do when investigating bloat is to execute something like the following...

Form allSubInstancesDo:
	[:f | f unhibernate.
	f bits size > 20000
		ifTrue: [f display.  Sensor waitClickButton].
	f hibernate].
Display restore

This will show you any big images that you don't think should be there.  If you want to track some of them down, then you'll have to get into an inspector and find out who's holding onto them.

Hope this helps
