I'm running Debian testing/stretch on a Thinkpad T520i. I'm using the internal trackpoint and mouse buttons, I've *disabled* the trackpad (in BIOS).
Following a recent update and reboot, my middle mouse behavior has changed. I can still use it to copy and past through the Xorg clipboard. Testing: I can still use it to copy and past through the Xorg clipboard. Yep, that worked. But in other contexts, it no longer seems to work via applications. - In Windowmaker, it no longer invokes the Windows menu (my default binding for that). - If I hold the middle button, *I cannot move the mouse pointer*. This applies *both in Xorg and on a console with gpm*. Which strongly suggests the problem *isn't* an Xorg, window manager, or application specific issue. - In the mission-critical application freeciv, middle mouse no longer brings up tile information. I'll confess I noted the problem here first. I'm somewhat suspicious it's the kernel.
