I have a Razer Deathadder Elite mouse and has performed great until recently, Now if I try to select rows of text it jumps all over and sometimes moves a few characters to different part of the document. I use this in Photoshop alot. In the crop tool for instance it will see the corner anchors but when I try to move any of these it does nothing. Another frequent issue is when I try to remove part of a filename in a save as dialogue window. It will sometime highlight the text but as soon as I lift my finger off the mouse button it will lose the selected area. If I try the same things using the mouse pad on my Ausus laptop it works flawlessly. Given the cost of these devices I thought I would try here to see if anyone has experienced similar problems and found a solution.
