Cannot Capture Screen on iATKOS v7 and iDeneb 10.5.6

[stranger87]

Hi All.
I have just tried to use iATKOS and iDeneb on my PC (Intel E2410, 1GB DDR2, HDD 160GB).
The Installation complete sucessfully. and i can use 2 OS ok.

But i found a problem, i can't capture screen by buttons: Shift+Windows+3, when i press them it don't work and don't save to desktop anything.

I tried use some software to capture screen ex: Jing, Screenium, layer, ... but when i opened it and press to capture, a windows jump to Desktop and request me shutdow by hold on power button on case.

I tried many times but it's not work.

May you guide me to solve problem? Thanks!
