Re: Strange error caused by post-command-hook.

Dear Martin Rudalics,

Thank you the suggestion. Before reading the following suggestion, I began
modifying the keyboard.c.

But I will try the following suggested tip first before compiling the
modified keyboard.c source file.

PS: Things get really strange. I tried the following tip, and found that
this doesn't really print anything of importance. It seems that the processing
that leads to the
"<< Press Return to bury the buffer list >>"
and probably the code that gets executed shortly after that is the candidate for 
the culprit.

Oh, wait, after a close look, I wonder what this 'tooltip-hide' is...

To wit: This is the *Mesasges* buffer after I added the
following hook:


((lambda nil (when post-command-hook (message "... %s" post-command-hook))) 
tooltip-hide)
<<< Press Return to bury the buffer list >>>
