I did something pretty stupid yes I admit it I got the "I have to update bug" I went to the new Internet Eplorer 7 beta and downloaded, evcerytime I kept using reportnet I would get this "do you want to access the clip board for this web page" I say yes but when I got to a point to add filters to my report it just kept poping up.
I took 7 off and now I am having the same problem with 6 CAN ANYONE HELP! I would go to my IT dept but they would laugh so I am trying to fix it my self, thanks.
I have run into a similar issue and I had to have my IT Department (X435) go and reinstall IE6 and the issue was resolved. :-\ The update bug is very easy to get!
I think if the ReportNet site was in Intranet Zone (or Trusted) it would work fine.
While still not "supported", I have been running both the beta and full version of IE7 for months with no ill effects, so it must be a setting in the internet options.
