Okay, I have been running Windows 7 since December and last week I noticed I had problems opening a new window or new tab in IE8. I have tried EVERYTHING. I registered dll's, reset the browser, deactivated/uninstalled IE8, shut off protected mode, messed with security zones you name it. I have been scouring the web for an answer. I enabled script debugging and saw that the site(s) were trying to do a window.open and the error that came back was no such interface supported. What can I do to fix this? It is inhibiting me from logging onto websites that I use at work that need to open a new window. Right now I had to use Chrome to even log this newgroup message! I would love to have a sure fire method or at least the ability to do a solid reinstall on Windows 7 of ie8 which currently does not seem available. I see folks switching over to all sorts of other browsers because of this. Is Microsoft uncaring about losing the browser war? I am surprised this problem hasn't been put to rest!
