Hmmm. I found that once you had the program installed, control f1 would get you everything you needed to know. Right clicking and selecting solve captcha was all that was required.

Yeah, every time I present the verbal problem thing, I get told it's too easy for bots to figure out all the combinations and permutations. It does sound like a good solution though.

I have encountered some sites where the problem is presented in actual text
and not an image or distorted image and this works well. The main issue with
captcha is the presentation in an image that is not readable with screen
reading software. While Webvisum works sometimes I have found it to be
inconsistent and as I use it infrequently I found it hard to find commands
and instructions on that particular site that were user friendly i.e. in a
place that was readily accessible.
