Every time I search Yahoo I get the following error.

Error

A Runtime Error has occurred.
Do you wish to Debug?

Line: 393
Error: 'SymRealWinOpen' is undefined

Please advise.

Check your popup blocker, like the article indicated.

I was getting this same error recently, although I don't know why it started all of a sudden. In addition to the "SymRealWinOpen" error (among other JavaScript errors), I also found that I could not go to some hyperlinked windows within a site. I would get "error on page" on the IE status bar. For one, I made sure that pop-up block software would not load. Don't forget that some packages such as Norton Internet Security have pop-up blockers, so you would want to disable that. I recommend a freeware package called Starter (http://codestuff.mirrorz.com/) which allows you to control whether programs load or not by checking or unchecking the program. Once you've disabled the pop-up software, reboot, and see if you still have the problem.

Here's an update on my posting from Aug. 24. To find out what was causing this problem, I disabled several programs from loading on startup, such as Pop-Up Stopper, Pest Patrol, Window Washer, AdSubtract, etc. My problem went away, so I used Starter (see my 8/24 posting) to allow one application to start up the next time I booted. Pest Patrol and Window Washer did not cause any problems, but when I loaded AdSubtract (an ad-blocker), the problem came back. I haven't loaded Pop-Up Stopper yet. The strange thing is that I have been running these programs all along, with no problems, so something happened (exactly what is anybody's guess!) to cause the problem to happen.

i have the same problem i tried everythin i know, like diable ad blockers and stuff and i still cant get the chelsea website to load, it keeps saying that error of symtac or w/e it is, please please help

When I go play pool on yahoo, I get this message:
"error line 49
symrealwinopen
do you wish to debug?"
As soon as I accept the proposition, I get another message telling me that no debugger is installed on my laptop. How could I do to fight this?
Thanks

@ mclen, perfect solution, I had the same error, and it`s gone now, thanks.

This happened to me every time I did I search on yahoo after I bought a new computer with XP. I now use Google to search and have encountered no errors. I think the problem might be with Yahoo's search engine.

Please note: This is meant for developers troubleshooting a prob on their site, not for the user that has script debugging turned on.

I had a similar "SymRealWinOpen" error on my home page. I use Homesite, and after doing a search through my code on that phrase, and having nothing come up, I decided to look at my code myself, line by line. I started with my home page, which written in PHP, references a header include. Silly me, I noticed that within header.inc I forgot to close _two_ of my closing tags (the greater than symbol on both lines). After uploading that fix, my "SymRealWinOpen" error went away.

What does that mean for you? I'm not sure, but perhaps you should see if you're missing any closing tags or such.
