Hey folks, bear with me, I'm new at this forum thing...my system is XP Pro, browser is IE6.0, and I leave my system on all the time, broadband net connection. For two years, I've always managed to get through the odd quirks, re-booting as a last resort. But now, out of the blue, I click on my address bar's pulldown menu, and nothing happens. I set my browser to open on about:blank, by the way, because it's fast. When I typed in an URL and opened on that page, and tried the pulldown again, it opened this time, but completely blank. I immediately checked History, no problems.
Other factors? I installed a google toolbar a few months ago, no problems at all. There's only one other thing I can think of -- I touched some weird combination of keyboard keys without noticing.
I went into all the toolbar elements, tried various things, no help. Even went into control panel, snooped around, couldn't find anything appropriate.
