Re: File error on open and sound reverb problem again

Stephen,

I've tested the file you modified on

- Mac OS X 10.6.7 / Etoys 4.1.1
- Windows XP / Etoys 4.1.1
- Windows 7 / Etoys 4.1.1
- OLPC Sugar 11.3.0 / Etoys 113

The fix holds except that on Windows XP & 7, the reverb comes back
intermittently. That is fine for now.

I would like to find out how to "modify beep" myself (where to find
the beep code) at some point so I can apply your code change to
another file if needed.

I can now proceed with having the volunteers help us on Mac and PC
machines. I will also be able to load demo files on XO-1 and XO-1.5
laptops to do demos at the Zambian Embassy in Washington, D.C.

I will credit the posters here in future announcements.

Mike
