It looks like GuiService doesn't immediately return the correct value for GetGuiInset. Because of this, the MouseLocation is always wrong for the isPosInsideRect checks in Menu / Window / Combo if you loaded too soon. In my case this leads to Menus never functioning as I consistently load too early in studio.
