I had a quick question, regarding 12\templates\layouts\Picker.aspx
dialog box, which pops up, when you click "browse" button in "advanced
permissions" for Site, page

I am getting a weird error, when I do a user search, when the matching
users are more than 200 , some junk HTML also shows up on results
section at bottom of user results section i.e.
<img width='1' height='1' border='0'

We are using WSS 3.0

Kindly could you give some pointers, where i should look to fix this
issue ?
