I can normally open IE7 alright. But when i click some IE shortcuts (from desktop, not directly in IE) the old IE one pops-up. Sometimes 3 windows will popup and an error. How can i fix this? I already tried reinstalling it yesterday but it doesn't fix. That's why i had trouble going Yahoo! Mail everyday using the shortcuts on my desktop.
Please post the specific popup information and Error message information.
And it is not clear from your first post, which icons you are clicking on that causes this problem.
