Finding a solution to the issue that was occurring with the scroll wheel on the G603. In overall, I found that it was a pretty straightforward and unanticipated solution to the difficulty I was having. Simply open a huge Word document (this will allow you to maintain control over the process), and begin scrolling down the pages using quick but light movements, ignoring any faults that may appear. When you reach the bottom, begin scrolling back up. When scrolling, you should avoid accidentally touching the wheel. Carry on in this manner for three to five minutes and then check to see if there are fewer difficulties. Turn the dial until the glitches disappear entirely. It worked for me, and this is with no disassembly or lubrication)) Most likely, when scrolling sharply, due to the significant friction, the contacts of the wheel and the encoder rub against each other and clean themselves. This occurs when the wheel and encoder are in touch with each other. In general, the success of this strategy was due entirely to chance, but it did the job. At this point, everything, including scrolling, functions without any hiccups. (I'm hoping it helps you as well)
