This can result in some nice crashes if !Sprites isn’t a Sprite file. I’ve not looked to see if it’s the !App code or the Sprites loader code at fault.

I tested on a fairly recent OS build and went right back to 3.11, they all crashed in the same way. I think I’d mistakenly named a PNG file !Sprites or !Sprites22 in a !App folder that was being looked at during boot. When I get a chance I’ll work out a Repro.
