I published one of our forms using the public permissions and embedded it using the Iframe embed code.  The form contains the signature field as we wish it to be used as a formal application.  On testing, I found that the signature worked great on Chrome and Firefox but not on Internet Explorer.  When I log into IE direct, the signature field works fine.  Is there a solution or workaround for this problem?  IE version is 11.

Thanks,

Scott
