FactoryTalk View Studio 8.10 - HMI Tag Window problem

Hi my friends. Have you that same problem like I have? When I am adding another HMI tag, when I click on empty row, it select two rows like you see on attached screen. I tried to restart system (VirtualBox Windows XPSP3), I tried minimize FT and reopen, but sometime its work but maostly not. I have to click more time for solve that. Its pretty annoying Sorry for my English.

My configuration
VirtualBox 5.0.8 r103449
Windows XPSP3 with all updates
FactoryTalk View Studio 8.10
I am running on laptop with USB mouse, touchpad is turned off and keyboard is free (no key is pressed).

Its not happening all the time. Now i Maximize HMI tag Windows and it seems be OK. Also works if I click between rows on that slider which is for resizing rows height.
