Go in Window on Mobile / Not Obeying Purge?

[Ralph DiMola]

That's one of my annoyances. Say you are inspecting a field and then delete the field the inspector does not close. One would think that if a control is deleted while an inspector for that object is open the inspector would close. This makes me wonder if the card retains some artifacts of the deleted field if it's deleted while the inspector is open?

I’ve found that if an inspector is open for something in that stack, purging is incomplete.

Caching is intended to speed up access, not to prevent ordinary behavior, so things not in use are purged as RAM is needed (same with cached images and other things).
