Safari 7, new windows issue.

Hello,

I'm experiencing next problem after installation of Mavericks and getting Safari 7 together with it.

Device: Macbook Air, Mid 2011, 1.7 i5, 4GB RAM.

Problem:

Overall Safari works OK, but on some different sites when I'm clicking on a link, which should open in a new window safari "thinking" for 2-3 sec. and open that after. I have another Macbook Air, absolutely the same with Safari 6.1 and previous OS – no problems at all.

What I have already done:

– Switch off all extensions

– Delete all extensions from Internet Plug-ins folder

– Even reinstall Mac OS Mavericks

Any suggestions?
