Hi Doug
Thanks anyhow, you got me on the right track.
Implementing your listener with a different condition works perfect, at least in
MSIE 5.5:
ondragstart:function(e){
if(event.button==2||event.button==3){
e.cancelDrag();
}
}
As my fix probably aint browsersafe, Im still looking forward to the bugfix
though.
For now I just need to figure out how to avoid the default browser contextmenu.
Regards
Brian Pedersen
