Wrong position cursor clicking fields of form

Hi Isomorphic
SmartClient v9.1 2014-02-22 - Power Edition
Internet Explorer 11
Clicking the fields on the first line of a form, the cursor is not positioned on it. To position it, I must click below each field on the form.
This only happens in Internet I Expolorer, in any case in other browsers like Chrome and FireFox.
Is it a bug of Smartclient?
Thanks in advance,
