editboxes dont update their layout when focus changes

[KlonZK]

they will remain highlighted (blue) after selecting another control.

quick fix: move self:Invalidate() in function Update() outside of the focus condition.

this report is for the old chili version distributed with zk, but the new version seems to have the same problem. untested because zk cannot run the new chili.

please test properly works fine afaik
