Original text on this page prior to its migration to StructuredDiscussions:
The links to Polynomial's Mouse Inverter do not seem to work anymore. The main link goes to Sendspace, and it always tells me that I've entered the wrong captcha and should try again. Of course, the captcha is answered correctly and there is a green check mark next to it. But then you click "Submit" and it gives you the aforementioned error message.
The alternative link goes to Filedropper, and it redirects directly to the main upload site. There is no download available.
I tried different browsers (Firefox, Chrome, Palemoon) with always the same result.
