Font used in Flash Player

Question

Hi Folks,
Need a little help here. I am running OS X 10.6.6 on a newish MacBook Pro. I began experiences some issues with Flash months ago, but didn't think much of it. It always plays video just fine, so no real problems there. However, text is the big problem. For example, on many local news sites, there is a video player with different video links to news stories. While I can see the picture of the video and watch the video, I cannot see any text that describes the video. In many cases, I can't even see the words Play or Pause. I know something should be there, but it never really bothered me until now.
I signed up for Weight Watchers and they use Flash pretty heavily for their site to record points, track foods, weigh in, etc. The Flash page that comes up for me does not display much text at all. It looks like there are some layout problems too. It is like much of the Flash application is missing. I tried uninstalling Flash Player and reinstalling after restart. No dice. Not only that, but now Safari wouldn't recognize the plug-in. I finally gave up and decided that it must be something in my system. So I restored OS X over the existing install (not a delete and install) and did all the software updates, and once again installed Flash. No dice. Nothing changed. Still blank places where text should be. Even the Global Settings and Settings box were all screwed up.
So, I headed over here and saw there is a 10.2 beta available. I thought maybe it would help. I installed it, and now there does appear to be more text where there was none before. The layout issues seem to be gone too. However, it still isn't all there. So, while I can see more of the Flash page, I still can't see all of it, just places where I know text should be. I can hover over some of this invisible text and a pop-up appears (apparently with invisible text too), so I know something must be there. Still can't make out the Settings box either. I was about to give up and thought I'd try it on a different account on this same computer.
Lo and behold, it works fine on the different account. No issues. The entire Flash page loads and looks great. It works without a problem. All of the missing text from the video players are there. The Settings box has all of its text as well.
I'm pretty convinced now that the issue must be a Font issue in my home folder on my account. This leads to ask the question: What font is used mostly in Flash? Specifically, which font is used mostly in the Settings box, since this is the font that doesn't appear in my user account. It is a sans-serif font. I can see the serif font. I'd like to know so that I can troubleshoot my Fonts folder and try to get this fixed. Anyone have any idea, or can you offer me a different suggestion to fix the issue?
Thanks!!

Yup,
I came back here to post that I had fixed the issue, and see your reply. Thank you very much. I had looked for a post just like that, but apparently I didn't look hard enough. So, thanks for replying!
The fix you linked to is the fix I tried and it does work. In the other user account on my Mac, there were no fonts in the user's fonts folder. There were dozens in my fonts folder. So, I figured that I would just get rid of the whole folder, since it's obviously not necessary. And it worked! There is obviously a conflicting font in the user fonts folder that is causing mayhem.
As an aside, After I had installed an update to Snow Leopard in the fall of 2010, I began having these problems. I also starting having problems when downloading documents in Microsoft Word around the same time. There was also invisible text there, too. I would have to select all and switch to a different font, which is clearly not a good solution. I was finally able to fix that issue. It too was a conflicting font. Must be a similar issue!  Probably a bug somewhere along the line...
Have a great day!
