ok I'm seeing some weirdness a reboot brings the issue back BUT I think its actually the 'touch keyboard and handwriting panel' process.
if I use task manager to quit that then click on keyboard iconto bring it back it restarts and the issue is gone.
it is since installing your latest beta though, but there was also various updates from MS...
I do have 2proccesses running though both called touchmousepointer one using 5mb and one 2mb of memory?
