Error messages when running simple scripts

[Monte Milanuk]

So... new to kivy, getting a bunch of messages spit out at me every time I run a script, some of which look like errors.

Thanks,

You can ignore that PermissionError, it arises because all potential input devices are queried but this one isn't available to the application.

We should probably suppress the printing of the exception message, but you don't need to worry about it unless you have specific input problems of some kind (and even then it's probably not the cause).

Okay, good to know.  Seemed odd, considering the first few scripts ran just fine.  Kind of disconcerting for a first impression, though.
