I am having trouble opening new windows and having slugish performance after I have been on my computer for a while. I usually go to FILE , New Window or Cntrl + N to open a new window. Usually after I open a few new windows, opening more is very slow, and even closing them by clicking on the red X in the top right upper corner closes them slowly.

 

Then when I try to open a link by right clicking on it to open a new window, sometimes it opens and sometimes it does not - especially when there are a lot of windows open already.

 

Furthermore, I have the taskbar line at the top where I can type in a new url, then I have the File, Edit, View, Favorites, Tools, and Help on the Second line. On the third line is a Star for Favorites, Home and Print.  Sometimes when I open a new page, only the 1st and 3rd lines appear and the 2nd line in the middle is missing.

 

I have run Norton anti-virus and Spybot and no viruses or spyware is found. 

 

I am only using 90% of my available space on my computer, and I ofter go to Tools and delete the cookies and temporary internet files.

If these problems persist, all I can do to clear it out is to restart the computer, and that usually corrects the problem.

 

I have only been getting this problem since I installed Internet Explorer 7, and never had it for Internet Explorer 6, but I don't know how to delete Internet Explorer 7 and change back to Internet Explorer 6.

 

Can anyone tell me what the problem might be? 

 

Please reply.
