222	"GUIRegisterMsg() and callback function ""chains"""	Ultima	Jpm	"It looks like there might be a bug/regression in the betas with regards to GUIRegisterMsg(), though I'm not exactly sure when the regression occurred. I've attached an example script (sorry it's a tad bit long, but it's simple).

As is, it behaves correctly, and the treeview root can't be expanded by double-click. On the other hand, if you return ''anything'', ''anywhere'' in the callback function chain, AutoIt decides it wants to handle the message, regardless of what is returned, and regardless of whether the return value even bubbles up back to the original callback function.

Regarding the function chain, ignore the For loops. I only added them to demonstrate the fact that it isn't because the function chain is taking too long to return that causes AutoIt to behave wonkily (it's something I considered at first)."	Bug	closed	3.2.11.11	AutoIt	3.2.11.9	None	Fixed
