Doesn't work at all. Regex, wildcard, etc. Nothing.

Searched, couldn't find anything. Whiled away an afternoon digging through the flags as well. My opera installation worked great for a long time, but now, for some reason, if I start typing a URL, there are new suggestions that pop up instead of all the places I usually go. For instance, for years I could type 'Wal' and hit 'Enter', and I was off to walmart.com to get groceries, parts, etc. Bam. Done. Now, my opera assumes I want to go to Walgreens.com. I've never been to walgreens.com, had no desire to go there, so I wanted to remove that suggestion. It turns out there there is apparently no way to do that?? Here's what I've tried:

• All the flags.
• Resetting the start page tiles.
• Reinstalling
• Clearing the history
• Looking for a little 'x' or similar when the URL is populating.

Any advice would be very much appreciated. I know this is a little thing, but I work on this things 8 to 12 hours a day, and I've got my boxes set up to run fast and smooth and implement my workflow. If I'm typing a new URL someplace that I always go every few minutes, and now they're all different, that's a stop I can't live with.

Thanks!
