I can see a couple of forms at that link. The top one appears to be a Contact Form 7 form. The bottom one appears to be from the MailChimp for WordPress plugin.
You have a very large amount of JavaScript, which is included in your theme, which appears to be preventing both forms from working. Using Firefox I see a lot more problems than the cursor issue you describe. I can't even get close to adding any info to your forms.
In this instance I would suggest you contact your theme provider to see if they can assist you with your problems.
