Problem switching between windows on taskbar

[Guest]

I'm running IE7 on Window XP SP2 and I'm having a problem with
window icons on the taskbar.
Whenever I have several browser windows open and want to switch between
them it always seems to take three or four clicks to do so.On the first
click the icon simply turns orange, otherwise nothing happens, the
selected window does not come to foreground as it should.
I suspect it's a problem related to Norton Antivirus but I've tried
switching it off and this doesn't seem to make any difference.Anybody
any ideas?
Thanks

I have a similar problem. It seems there must be a control setting that
governs this. I use Alt-tab to switch between Windows, however on my latest
lap top computer the windows do not come up on the screen as they should,
especially Explorer and Powerpoint windows (or the latter seems to dominate
the others). I have to minimize all other windows in order to see one, at
times.

Are there any suggestions out there for solving this problem?
