Can somebody explain this to me (uploaded it today)

I have this problem on Mac Pro from sig and Logitech G300 mouse, and every other USB mouse. Sometimes even happens that object I grabbed to drag (icon, folder....) just lets go without me releasing mouse button.

I read that many peaple have problems with mouse or laptop trackpad on Mountain Lion. Is there fix for this ? It is very annoying, especially in Photoshop and Maya :(

I have seen this with a suboptimal tracking surface for the laser or optical sensor. Try using it temporarily with a piece of paper under the mouse and see if the problem goes away.

Problem solved.

One one of three DELL U2414M monitors, beside DVI, I used one Dsub connection for second computer. Removed Dsub - problem gone. Probably problem with ground or just bad Dsub cable.

What a relief !
