Hey,
It seems you are using own XVM config file which binds Minimap Zoom to key coded as 17. However some hotkeys in XVM has changed lately and 17 now stands for "W". Change the hotkey in your xvm.xc to 29 (CTRL) and everything should be fine. I had same issue myself.
"hotkeys":
{ "minimapZoom":
{ "enabled": true, "keyCode": 17, "onHold": true }
}
should be changed into this:
"hotkeys":
{ "minimapZoom":
{ "enabled": true, "keyCode": 29, "onHold": true }
}
