Hello Takayuki,
I really appreciate you personally responding to posts in this forum.
I just switched to the default WP theme and deactivated all other plugins.
I also made a clean install of the plugin before I tested this.
I still have the same problem, I can't click on any links that are on the same page as the form.
This is what my form field looks like in the Contact Form 7 Preferences, for example the link on top is visible, but is not clickable. Even if I put it inside the Form div. Perhaps this excerpt should show something wrong with my code.
<p><a href"info@gsdnyc.com">info@gsdnyc.com</a></p>
<div id="form">
<div class="formheader">Your Information</div>
<div class="formleft">
[text* your-name class:forminput watermark "Your Name *"] </p>
[email* your-email class:forminput watermark "Your Email *"] </p>
</div>
<div class="formright">
[text your-subject class:forminput watermark "Subject"] </p>
[text telephone-number class:forminput watermark "Telephone Number"] </p>
