How to turn off mouse (or touchpad) scrolling when running vim in an xterm?
Just updated 13" macbook pro (mid-2010) from Snow Leopard (10.6.8) to Yosemite (10.10.1). Previously, when running vim in an xterm, scrolling with the touchpad did nothing inside vim, it just scrolled the xterm history back so I could see what I had done before executing vim. Now, the same scrolling action (either with touchpad or with an external mouse with scrollwheel) moves the cursor position inside vim (if I'm in navigate mode). I want to turn this feature off. I'm sure some people like it but I do not. Anyone know whether this is something to be blocked by vim settings, or perhaps something in the xterm settings I need to change? Vim version is 7.3 (2010 Aug 15), which must be a slightly later version than I had under the original operating system, since I got it July 2010.
I've tried modifying various vim settings, but to no effect. I haven't found a comprehensive list of such settings to try systematically.
MacBook Pro, OS X Yosemite (10.10.1)
