3875	GUICtrlSetResizing() performance	KaFu	Jon	"Hiho Team,

maybe you saw my posting in the open help forum about GUICtrlSetResizing() performance.

I've tracked it further down, and it seems that as of 3.3.15.5 the Windows Message pump for a certain Window is engaged on the first call of GUISetState() for that Window.

This degrades the performance of GUICtrlSetResizing() after that call drastically, and the time increase per call is also proportional to the amount of controls.

100 calls in 3.3.14.5 take 0.2ms, in 3.3.15.5 690ms on my computer.

Best Regards
