If you're having trouble clicking links, you might try the same website 
in a different browser or with a different screen reader. I've got 
Firefox and Internet Explorer on my system, and some web pages are more 
accessible in one browser than in the other. Firefox tends to be the 
more accessible one, but there are lots of exceptions. I also have both 
Jaws and NVDA installed. Jaws frequently fails to report links as links, 
and cursor routing and mouse simulation don't always work. Again, NVDA 
tends to work better, but every now and then, Jaws prevails.

On the subject of Capchas, Webvism is a life saver. I tried it 
unsuccessfully a couple of years ago. Then I tried it again this year, 
and I've had a good experience. It doesn't always work, but it works 
most of the time, so I don't have to wait for someone sighted to be around.

I agree with the rest of you. Most of the audio capchas I've heard have 
been too hard to work with. The sighted people who help me with the 
visual capchas also complain about how hard they are to figure out 
because characters appear in different sizes and orientations and 
because they're often superimposed over a busy background; also, 
sometimes the characters are spinning and need to be clicked 
individually to be seen.

Every once in a while I encounter accessible capchas I really like. They 
say things like, "In the box, write how much three plus four is," or 
"Write the three color words in the following sentence. The green grass 
over the white picket fence is under the gray clouds." I wish those 
would catch on.
