It is not the first case. Actually, when I open TeXmacs the first time, and try to close the window, I notice the yes or no choice.  But this time it is really not that case, the Activity  Monitor also shows red line on TeXmacs with not responding.

Subject:  Re: [TeXmacs] No response after CMD-w to close window on TeXmacs 1.99.4 OS X

When I show students how to use TeXmacs, sometimes I find that they overlook a prompt at the bottom of the main window, e.g. a question about saving files before quitting. This can cause the symptoms you describe: TeXmacs won't do *anything* until you answer that question.

I think there is a way to set preferences to have TeXmacs ask such questions appear in a separate pop-up window.

Or, it could be a bug I've not seen.

Hi, guys,

This is Steven. I have one question while using TeXmacs 1.99.4 OS X version. When I press CMD-w to close a file, the TeXmacs window turns to be dead (not responding). The only way is to force to quit.  I tried  to reinstall it, but still the same problem there. However, after downgrading to 1.99.1, this problem does not show up.

Any ideas?

Thx
