When I download something to my desktop, or insert a CD or flash drive, the icon appears on my desktop. When I have conky running, the icon sometimes appears in the top right corner, underneath conky; where I can't see it.

How do I stop this happening?

My .conkyrc is pasted below. I didn't write it all myself, so I'm not entirely sure what I need to change, or what parts are relevant for this particular question...

Conky solutions have been offered, but perhaps these aren't the best way of approaching it. What I really want is to stop icons even appearing in that part of the desktop window: that is, I want to make part of the desktop real estate "off-limits" to new icons appearing on the desktop.
