I can't seem to reproduce this.

What is printed to the main Pd Window when you start Purr Data?

Also, try right-clicking on the main Pd Window (or whatever the Mac equivalent is for right-clicking)
and choose "Inspect Background Page". Then click the "Console" tab and tell me if you get any
errors there:

a) right after starting Purr Data
b) after trying to open a new patch for the first time
c) after trying to open a new patch the second time
