Streamed IE issues with new tab

Hi all,

I have a small issue, I have a streamed IE from a RDS farm with 2012r2 up to date and SEP (Symantec endpoint protection). We use also view 7.01 connection server and view agent. My issue is when we open a link in a new tab. IE is freeze for one minute until the next tab is opened in a new window. Of course if a have a full desktop session on IE farm  no problems, only when is streamed. I couldn't find any errors in view or windows.

Any suggestions?

Thanks.
