Zoom functionality from the scroll wheel suddenly stopped working after I enabled the toolbox plugin in a fresh install of 2004 SP3.1 (WinXP Pro) today. It was working properly before this. I have tried disabling the add-in, restarting SolidWorks, rebooting the computer, different part models, etc., all to no avail. It now will simply not use the scroll wheel, though the scroll button works fine for rotating. The wheel continues to work correctly in other applications.
I also tried resetting the mouse settings in Windows. In my experience, it is best to set the scroll wheel to 'MS Office Compatiblity' in the mouse settings from Windows XP Control panel, otherwise SolidWorks will often pan instead of zoom when using the scroll wheel.
Thanks for any help.
