Trackpad Handwriting Bug

I've been having issues with the trackpad handwriting input. Sometimes it does not show up and sometimes it won't exit it when I press the keyboard shortcut to (de)activate it (Ctrl+Shift+Space). It will work again if I open system preferences; I do not do anything in system preferences, I just open it.

I do not use it enough to know when it started or if it was after a particular program was installed, but enough that it is getting really annoying.

Is anyone else having issues or know of any issues? I tried to do a google and mroogle search with no luck.

Thanks in advance.

 

any ideas of what the problem might be?
