settimeout and scroll problem!

[VBmim]

I am trying to let my window scroll continuously while I am pointing a picture with my mouse (arrows, one up and one down).
What happens is if I point either one of the pictures, the window keeps scrolling till the end without scrolling, even if my mouse is at an other place by then...

here is my code:

//this function is called in the mouseover event of my UpArrow picture
function ScrollUpArrow ()
{
BoolScroll = true;
OutMouse = false;
while (BoolScroll == true)
{document.frames["HelmenIFrame"].window.scrollBy(0,1);
window.setTimeout("ScrollEnd()",10);
}
}

//this functino is called in the mouseover event of my DownArrow picture
function scrollDownArrow()
{
BoolScroll = true;
OutMouse = false;
while (BoolScroll == true)
{document.frames["HelmenIFrame"].window.scrollBy(0,-1);
window.setTimeout("ScrollEnd()",10);
}
}

//This function is called in the MouseOut event of both pictures
function MouseScrollEnd()
{OutMouse = true;}

function ScrollEnd()
{
if (OutMouse == true)
BoolScroll = false;
}

What the hell am I doing wrong!!

pleazzz help me!

To use and share BoolScroll and OutMouse values in more than one function declare them globally, outside the scope of any function --

  var BoolScroll = true;
  var OutMouse   = false;

Then all of your functions will use the same BoolScroll, OutMouse -- mouseover and mouseout will have better communication.

thanx for the reply!!

actually, I found what my problem was... (well, I think I have... ) While my script is in a while loop, it seems like it can catch no event at all, so I skipped the while-loop and did it like this:

function scrollDownArrow ()
{
OutMouse = false;
document.frames["HelmenIFrame"].window.scrollBy(0,2);
window.setTimeout("ScrollEndDown()",5);

}

function scrollUpArrow()
{
OutMouse = false;
document.frames["HelmenIFrame"].window.scrollBy(0,-2);
window.setTimeout("ScrollEndUp()",5);
}

function MouseScrollEnd()
{
OutMouse = true;
}

function ScrollEndUp()
{
if (OutMouse == false)
scrollUpArrow();
}

function ScrollEndDown()
{
if (OutMouse == false)
scrollDownArrow();
}

voila! I hope this helps others with a similar problem...
