Using a default filename with a forward slash (not a backslash) would cause input() boxes of "as file" without a cancel option to loop indefinitely. The loop problem has been fixed, and using a forward slash will now be treated as the correct backslash.

Does the problem occur:
Every time? Or how often? Everytime
In other games? Don't Now
In other user accounts? N/A
On other computers? Don't Know

When does the problem NOT occur?
Always does.

Did the problem NOT occur in any earlier versions? If so, what was the last version that worked? (Visit to download old versions for testing.)

Do not put a default...ruins the purpose though.
That sounds a lot like your OS has become unstable. Have you tried this after a reboot?
I can confirm this using Windows 7 Ultimate.

Using the verb causes DS to freeze and become unresponsive.
