Hi guys. I have tried to solve the problem alone but without results. I want to install ATT, my PC is in signature. For first i get DLL issue. Solved copying the DLL downloaded from internet in the directory. Now i can start ATT but after any seconds i start to have flesh on my monitor. When i move the mouse, open new windows o simply stay stopped, i see differente "flash". Like the frame is sent in a different position. For example i see top bar or side bar in the middle of the monitor, or in random position. These frame flash are fast and discontinuous and they growth with moving mouse or opening windows. I have tried to change many setting but without result. Can you help me? Thank you.
