Re: [Audacity-devel] Audio I/O bugfixes

[julian g. <jul...@ja...>]

Yep, that seems to have done the trick.   Doesn't core dump anymore and 
also no scrolling to the start each time play is stopped.

I have found another bug:

If you create a label track and put a lable on it, then save the project 
then reload I get the error:

Error: mismatched tag at line 477

This is being generated by expat.   Is this an error in the dtd, is 
there code to load label tracks?   I am investigating but this is a tea 
break activity at present.
