returnclk(xx,this)

[hot_shot]

Hi all,

I was wondering whether anyone else has seen these type of errors in their logs. I occassionally get url requests like:

lost.cfm?lost=391onmousedown=returnclk(this,res

lost.cfm?lost=391 would be the normal part, but for some reason the extra
"onmousedown=returnclk(this,res" part is added.

My guess is it's some sort of pseudo browser that is screwing things up. Anyone else see these weird things.. A search for 'returnclk' on google only found a handful of other people with the same question, but a TON of these in logs. No answers... hopefully you guys have an idea, I'd just like to know.
