Re: Aquamacs running without frames may lead to hang

[David Reitter]

This reproduces easily. It’s a lisp-level infinite loop from what I can tell. Would someone like to give it a shot? Hayo?

Clicking finally on the red closing button of this last frame makes Aquamacs hang, so that it can only forced quit.

Hi David (and Konrad),

I *can* reproduce this, and would like to help out fixing it. I have no
idea where to start looking though. If you have any tips on where to
start looking, please let me know! Also if you have any tips on how to
debug the (lisp) code, that would be helpful too (I have no experience
here yet, I'm afraid).

Cheers,
Hayo

After the recent changes in aquamacs-frame-setup, this problem is still present.

[David Reitter]

Not much progress on this one.
I can reproduce it with *grep* buffers, but not with others like *Messages* or *Help*. Maybe the problem is related to process based buffers.

I also reproduces when using Command-W to close the buffer.

close-current-window-asktosave is maybe something to look at next.
