Not fully fixed. If the control is in a controlsGroup, it doesn't work properly, it uses the position of its controlsGroup parent, instead of its own absolute position.
In other words, to do the backward selection you have to move the mouse all the way outside of the controls group for it to work (forward selection works fine though):

_disp = findDisplay 46 createDisplay "RscDisplayEmpty";
_grp = _disp ctrlCreate ["RscControlsGroup", -1];
_grp ctrlSetPosition [safeZoneX+0.2*safeZoneW, safeZoneY + 0.2 * safeZoneH, 0.6 * safeZoneW, 0.6 * safeZoneH];
_grp ctrlCommit 0;

Do you know if that is new? As I recently touched exactly that code.

Did you guys try verifying the game data via Steam?

That's because it's not Arabic. It's Persian:

this command would have several applications.

I did this search in an AiO config:

idcSearch[ ]*=[ ]*-1

but no result.

But isn't this dangerous?! Especially if it also supports command line arguments

repro script doesn't work because you only have single level of items.
_tree tvAdd [[0], "Item 2"];

works tho

is there a example of displays that change the cursor?

also wrong: forEach. Example shows string as the "command", which should be code.

I think this is wrong too:

createSimpleObject [shapeName / className, position [,local]]

Also see: T155705 and T155704

inAreaArray is also already really fast isn't it?

I figured since playSound3D does, the playSound should too.

Isn't it possible to update ctrlCreate so that we can change the style there?
e.g.

_disp ctrlCreate ["RscText", -1, controlNull, ST_LEFT]
