launching the application from a terminal or terminal emulator (konsole for example) would usually output debug messages to the terminal during use. not all softwares provide any output at all however.
failing that you'll just have to assume this software to be unstable. i personally have never used "seamonkey" and cannot comment on its current state. does it appear in the portage stable tree or is it masked for any reason?

Hi TrickyRic,
launching the application from a terminal or terminal emulator (konsole for example) would usually output debug messages to the terminal during use. not all softwares provide any output at all however. I did not start application on terminal but from menu bar.
failing that you'll just have to assume this software to be unstable. i personally have never used "seamonkey" and cannot comment on its current state. does it appear in the portage stable tree or is it masked for any reason? It is not only limited on SeaMonkey. It occured on random occasions on different environment, editing text with "nano", "browsing Internet", "scrolling a page, either webpage or text, with mouse wheel, etc.
I suspect whether Xorg caused PC hanging. I did not encounter this problem while running console, runlevel 2/3.

does the following output anything?
cat /var/log/Xorg.0.log | grep EE
it could easily be that now you have a new xorg.conf, you no longer experience these issues. if you do though then you may want to try using another mouse protocol.

Hi TrickyRic,
does the following output anything? cat /var/log/Xorg.0.log | grep EE
(WW) warning, (EE) error, (NI) not implemented, (??) unknown.
(II) Loading extension MIT-SCREEN-SAVER
Others noted with tks.

Hi TrickyRic,
Further to my late posting, I think most likely the hanging was caused by the mouse. Can I try another protocol? If YES please advise how to make the change.
$ cat /etc/X11/xorg.conf.....
Section "InputDevice"
# Identifier and driver
Option "Protocol" "PS/2" # PS/2 Mouse
Option "Device" "/dev/input/mice"
# When using XQUEUE, comment out the above two lines, and uncomment
# the following line.
# Option "Protocol" "Xqueue"
# Mouse-speed setting for PS/2 mouse.
# Option "Resolution" "256"
# Baudrate and SampleRate are only for some Logitech mice. In
# almost every case these lines should be omitted.
# Option "BaudRate" "9600"
# Option "SampleRate" "150"
# Mouse wheel mapping. Default is to map vertical wheel to buttons 4 & 5,
# horizontal wheel to buttons 6 & 7. Change if your mouse has more than
# 3 buttons and you need to map the wheel to different button ids to avoid
# conflicts.
Option "ZAxisMapping" "4 5 6 7"
# Emulate3Buttons is an option for 2-button mice
# Emulate3Timeout is the timeout in milliseconds (default is 50ms)
Option "Emulate3Buttons"
# Option "Emulate3Timeout" "50"
# ChordMiddle is an option for some 3-button Logitech mice
# Option "ChordMiddle"
EndSection
.....
TIA

the output you posted is of a comment within the log and safe to ignore. no other outputs suggest xorg is working fine.
to change the protocol used, simply reference something other than PS/2 (which your currently using) in the inputdevice section of xorg.conf. different protocols support different technologies and sometimes at various reliability. there's a few protocols today, but for a regular usb or ps2 mouse you can usually get away with Auto (note you may find the system just uses ps/2 though, if you allow it to auto select):
Option "Protocol" "Auto"
personally if Auto doesn't do any better, i'd start by trying IntelliMouse, ImPS/2, or ExplorerPS/2. while these were geared more towards microsoft scroll mice, they do tend to work quite well on other similar devices.
you can do much more than changing protocol with mice. for example, if you have a fancy mouse with extra buttons, you can use a combination of the Buttons and ZAxisMapping options, together with xmodmap to configure the extra buttons and scroll wheels etc.
please note though that changing protocols can sometimes alter which pseudo device you need to use, so /dev/input/mice may become say... /dev/psaux. don't panic if you appear to lose your mouse altogether, its most likely just linked up to some unusual file.

Hi TrickyRic link,
Tks for your advice.
Finally I recall that I met the same problem on Ubuntu 6.0.6 previously. The solution was on /boot/grub/grub.conf adding "noapic" to the end of the line:kernel (hd0,0)/boot/linux-2.6.17-gentoo-r7 root=/dev/hda2 noapic
It is the problem of Xong causing the PC to hang. I'm now answersing this posting on Gentoo box which has been working for more than an hour without problem.
Others noted with tks.
B.R.

Hi TrickyRic,
The Gentoo box has been working for amost half day without any problem. Emerge packages on desktop console went through smoothly without causing PC hanging.
