Problems filling out an online webform with my Mac.

Can anyone please help me?!

I have build an online webform on my website (with Concrete5) and at first it was working perfectly.

Then suddenly the top halve of my webpage  appeared not clickable anymore, including the navigationbar and searchfield. This while I haven't changed anything and earlier I experienced no such problems!

 

Now my friend tells me on a Windows computer there are no problems. Can anyone please tell me how I can fix this problem for Mac users?

I have tried it with Safari, Google Chroom and FireFox.

I hope someone can help me with this.

 

Thanks in advance!

Kind regards,
