x3dom rotation not working when using toAxisAngle(). Element follows mouse correctly, but does not rotate correctly

I have a page that I am creating that is similar to a game with a bird's eye view. I am trying to move a x3dom element on the x and z axis based on a mouse move event. It works except it isn't rotated correctly. The element called placeholder is the one that I am moving based on the mouse coordinates. Under the function squaremousemove(), you'll notice the rotation of rot[1]. I tried replacing this with rotateIncrement which is how I rotate all the other elements, but this didn't work. The place holder is suppose to have the same rotation as the square. Any ideas?

while (have_posts()) : the_post(); ?>

Correctly vs Not Correctly Installed Heatsink
Hi ,I just wanted to show you , my personal experience with a not correctly installed CPU Fan, Both test were made using the CPU test suite of PCMark05 and I read the temperatures with SpeedFan 4.32 , My processor is a Core 2 Duo E6600 with stock heat sink in a Gigabyte 965P-DS3 board.
I didn't use a more reliable stress test because probably I'd had fried my CPU :S
