Javascript onblur prevents users to select dropdownlist

[simo sentissi]

Hello

I have a popup window that I would like to keep on top so I am using the
foloowing javascript:

window.onblur = function()
{ setTimeout('self.focus()',100); }

it keeps my popup window always on top but the problem is that I have a drop
down list on the form and whenever I try to select elements in it, the list
disaper on me really quickly so I do not have time to selct any thng from
it.

I would like to know how I can have a window to always stay on top wihout
haveing sich problems ?

Thanks a lot
