IE drillthroughs openng in new window

[ahg]

Hi,

I have a report that contains a drillthrough to another report. The drillthrough is not set to open the report in a new window, however, in internet explorer the drillthrough report will open in a new window instead of the existing one. I'm guessing it is a setting in IE rather than cognos as the report runs as expected in Firefox, but I was wondering if anyone had come across this problem and knew the setting I need to change?

Thanks..
