Mouse Overs While Dragging...

Last month I created a little snippet for mouse overs while dragging. The original snippet is on a corrupted HDD and I'm working on retrieving it ATM. As God apparently hates me, though, it seems I'm going to have to redo all that work (this plus the rest of the months coding). I thought that maybe I would come here to see if anybody had a better way to do this. Here is a recreation of my original snippet.

obj/button
    var
        multi   //multi-tiled buttons
        over    //whether or not the mouse is over it
        multitype   //mutli-tiled buttons have a type so we can find it the other parts of this button
    single
        multi = 0
        over = 0
    multi
        multi = 1
        over = 0
mob/buttonuser  //lawl
    var/obj/button/BO   //the button that the mouse was last over
    MouseDrag(O)
        if(!istype(O,/obj/button))  //if it isn't a button ignore it
            if(src.BO)                                          //if a button was saved as being the last one the mouse was over
                if(BO.multi)                                    //and if it's a multi-tiled button
                    for(var/obj/button/multi/M /*in wherever*/) //it finds other multi-tiled buttons
                        if(M.multitype == BO.multitype)         //and checks to see if they are part of the last button
                            M.icon_state = "up"                 //if they are, it changes their icon state
                            M.over = 0                           //and tells it that the mouse isnt over it any more
                else                        //if it's not a multi-tiled button
                    BO.icon_state = "up"    //it just changes the last button's icon state
                    BO.over = 0              //and changes the over var. too
                src.BO = null
            return
        var/obj/button/B = O
        if(!B.over) //if the current button isn't the last button the mouse was over
            if(BO.multi)
                for(var/obj/button/multi/M /*in wherever*/)
                    if(M.multitype == BO.multitype)
                        M.icon_state = "up"
                        M.over = 0
            else
                BO.icon_state = "up"
                BO.over = 0
            if(B.multi)
                for(var/obj/button/multi/M /*in wherever*/)
                    if(M.multitype == B.multitype)
                        M.icon_state = "over"
                        M.over = 1
            else
                B.icon_state = "over"
                B.over = 1
        else
            return


This isn't exactly as the original one was but it's pretty close. The original one was shorter because it was specifically for one type of button. This one covers more bases. I know the original snippet worked perfectly but I'm not sure if this one does as I made it like three seconds ago.

Improvements? Questions? Comments? GTFO?

EDIT: I also note that, before my HDD went down, I never found a way to revert the button if the mouse moves from a button to, well nothing. Apparently the MouseDrag() doesn't get called when the mouse is dragged over nothing. Bummer.
