Make sure you take a snapshot of the perspective after collapsing them (and make sure the perspective is set to restore expansion settings). If some grouping wasn't present when the perspective was first created, the grouping's expand/collapse setting might not be saved as what you want. Suppose a project then lands in that grouping. The grouping now appears and might be expanded. I find that if I collapse it and take a new snapshot, then the grouping stays collapsed.

Cheers,
