Noticed that Save/Open dialogs opened by Chrome don't get hooked properly. Save/Open dialogs from other Apps (checked Notepad and RPG Maker VX Ace) hook fine and have the style that Explorer windows have, Chrome just ignores the styling fully and behaves like standard 11's Save/Open dialogs.
Just to compare, heres how its meant to look. (The blurryness is just cause this version of RPG Maker doesn't support HiDPI.)
