IE crashing after about 70 open/close event

[István Sebe]

Hi,

I have to open links (about 3000) and then close them.
The problem is, that after 70 open/close event the IE (FF not supported
in our WebServer) crashes, stuck in memory and the script collapses.

The script:

def link_clicker()
if $br.frame(...).exists? then
$br.frame(...).lis.each do |linke|
linke.click
$br_new = Watir::IE.attachurl,linke.href)
if not $br_new.pageContainsText(text) then
puts "No match" #only debug feature
end
$br_new.close
end
else puts "Doesn't find list!"
end
end

Any ideas how to solve the problem, please?
Thank you
