Frozen cursor after making changesto font face & size[FIXED]

But cursor frees up after I tab to another window on the computer and then back to Scrivener. Sometimes, it remains frozen even in the tabbed window but after tabbing a couple more times between the two windows, the cursor moves again and I can resume typing.

Hardware: ASUS eeePC 1000H

This doesn’t seem to happen to me.
