/*
Pop-Up implementation notes.

Pop-up look and feel are maintained in the popup divs on the page by using the associated styles and images for either the blue popup or orange popups (or any additional colored popups we may use.

Each pop-up will require slightly different parameters, based on where they are on the page, and the amount of text they contain.

Shim divs and all tooltip divs should be at the top of the HTML portion of the page. (immediately after the body tag)

setLyr is the main function for placing the tool tips, each one will have completely different numbers because each tool tip will be different heights, widths, and
have different starting positions.

*/
function handleOut(elname) {
// hides all popups, parameter is the div name
// function called on onmouseout of hyperlink parameter
var shim = document.getElementById ("shim") ; // this is the univeral shim used by all popups to cover the any select boxes
shim.style.left = "-650px"; // put it off the screen
d = document.getElementById(elname) ;// get the popup 
d.style.left = "-650px"; // put off screen, this number would need to be made larger if you had a really wide popup div
}

    /*
    Required parameters:
    obj1 - the element to reference location from, generally the hyperlink, this is the starting location of the popup.
    lyr - the DIV to position - the divs are positioned off the page to start, the html is at the top of each page for each div
    shimwidth and shimheight - must equal the height and width of pop-up
    mouseoffset X and Y - how far from mouse to pop-up
    windowSizeAdjustX - (not for Safari) how many pixels to move the x coordinate if the window is small
    windowSizeAdjustY - (not for Safari) if the top of the page is greater than this then move the pop-up down
    maxWindowWidth - Used for Safari - if the window width is less than this then move pop-up to the left 
    maxWindowHeight - Used for Safari - if the top of the page is greater than this then move the pop-up down
	
	 example of use below:
	 Format:
	 <a href="#" id="c2" onclick="return false;" onmouseover = "setLyr(obj1,'lyr','shimwidth','shimheight','mouseoffsetX','mouseoffsetY','windowsizeAdjustX','windowsizeAdjustY','maxWindowWidth','maxWindowHeight');" onmouseout = "handleOut('popup2');" >Our Security Pledge <img src="/images/icon_lock.gif" alt="Amica Secure" border="0" /></a>
	 Size of the Orange tool tip example:
	 <a href="#" id="c2" onclick="return false;" onmouseover = "setLyr(this.id,'popup2','300','165','00','175','275','90','300','190');" onmouseout = "handleOut('popup2');" >Our Security Pledge <img src="/images/icon_lock.gif" alt="Amica Secure" border="0" /></a>
	 Size of the Blue tool tip example:
	 <a href="#" id="c1" onclick="return false;" onmouseover="setLyr(this.id,'popup1','300','165','70','185','275','90','300','190');" onmouseout = "handleOut('popup1');" ><img src="/images/icon_tooltip.gif" alt="" border="0" /></a>  
    
	requires the browser.js script for browser detection
    as well as findPosX and findPosY, which find the referenced object's position on mouse over of the hyperlink element
	- findPosX - for locating X of the mouse over point
	- findPosY - for locating Y of the mouse over point
	- handleOut (makes tooltip disappear)
	- setLyr - for moving a tooltip
