I have been using a wireless Microsoft mouse for months now and have had no problems. I have not Blendered in a while, and have downloaded some mouse updates since I last used Blender. Today I just discovered that middle click and drag is causing the window to get smaller instead of manipulating the 3d view . I don’t know how to change this setting- can someone tell me? I am assuming it was the updates, but I am open to whatever suggestion you have. Thanks.
Middle mouse messed up only in Blender I assume? You went control panel mouse properties and looked? You push the scroll wheel and it scrolls without scrolling sounds like maybe, possibly you got a short in the mouse?
Hope that helps…
Thanks guys. I found the problem.
