Guys,
I' writing a small auto window generator script, but am having a slight problem.
The functions I have to move the window while holding the mouse button down are not working corectly.
If you move the mouse too quick, the window gets left behind.
Any ideas...????

Seeing a working version of the script will probably help us to figure out what's wrong.

hmm... I'm a bit skeptical of the onmousedown in tr tags. Not that it's totally unsupported but that just seems hinky to me.


othewise.

You shouldn't need two functions onMouseDown and onMouseMove. Just the mousedown should be sufficient. I'd put the onmousemove in the general body tags...
window.onmousemove = track;
function track{
mousex = event.x;
mousey = event.y;
}

There now you have the mousepos in 2 vars:
relative to the whole page.

Yup, yup, that's exactly the problem. You need the onmousemove to be effective *everywhere*. When the user moves their mouse out of the TD, the TD's onmousemove event is no longer called, so the window's position is never updated.

So bitdamaged's solution should work.

Good script though.

Thanks all.

Just adding 'document.onmousemove=moveWin' into the main script area works a treat.
Can now develop this script further.......
