Works For Me (tm). Mouse behavour changed in 0.13 (compared with 0.12) a bit - now, without the usual in such cases -usbdevice tablet, guest mouse does not follow host mouse, because they don't match anyway. You have to switch to guest (Ctrl+Alt, or hit mouse in guest window) to activate guest mouse.
