I just bought Dell Desktop XPS 8300 system with 24 inch ST2420L Full HD LED Monitor. The monitor is so sensitive that even just touching a folder opens it although I have selected double click to open in folder options. It is same with menu bars & some files too. Drop down menus snap right back up. Dell tech support spent an hour but couldn’t do anything. I am using the Native Resolution of 1920X1080 It has NVIDIA GeDorce GT 530 Video Card & I installed the Latest drivers too. I am using the DVI port for connection. The system came with Win -7 Home Premium but I installed Win -7 ( Ultimate ) on it. Any help will be much appreciated. Thank You
