Summary: turning off dsp with loadbang doesn't work

Initial Comment:
If dsp is on, opening a patch with:
[loadbang]
|
[; pd dsp 0]

doesn't turn it off.
For an example, turn on dsp and open the help file for bang~

I tried it in pd 0.42-5 and pd-ext 0.41-4 rc1 on winxp

Message:
This is because Pd saves the dsp state, turns off dsp when loading patches
and then restores the dsp state again when loading is complete.  So any
changes to dsp state while loading will be lost when the dsp state is
restored to what it was before loading.

Probably Pd should restore the dsp state before triggering the loadbangs.

Try swapping the order of the pd_doloadbang() and canvas_resume_dsp() at
the end of this file:

http://pure-data.svn.sourceforge.net/viewvc/pure-data/trunk/pd/src/m_binbuf.c?view=markup

But this "fix" might have other ramifications....

Message:
p.s.- inserting a [del 0] after the loadbang will make it work
