Ken and Group:
I am really enjoying this exchange of information. Also, I send my
apologies to the group for this tangent thread.
First let me say that I am not a part of the Microsoft Cheerleading
squad. I just believe that their OS is the one of choice for most
businesses and it becomes incumbent upon the user to make it work as
best he/she can.
In the past I have found that the Real Audio package had caused some
glitches on my machines. I have also found Norton's anti-crash software
to be an oxymoron. Additionally there are known bugs with McAfee that
will bring a machine to its knees. Just check out their websites.
Windows obviously does not like anything getting in-between the OS and
the hardware. So when Real wants to take control from Media Player or
McAfee Firewall wants to filter packets, the OS wants to compensate and
a percentage of the time there will be a lock-up. Ever try running
McAfee Net Watch and checking your through-put? Aside from the obvious
reasons, why does it take so much overhead that it reduces the
though-put by 30%? Wonder why it locks up the browser? (Rhetorical
questions).
BTW, I also like to sit near the emergency exit:-!

Hi all,
First of all I would like to apologize to those who are annoyed by this
discussion, which has centered on reliability of computors running
windows. While it is not about Ten-Tec radios, I think anyone can see
how it relates when more and more of the functions in newer radios are
totally dependant on microprocessors and the firmware running on them.
Now back to the windows reliability issue... The latest computer I have
here at home is exactly as delivered by Dell, with just one addition, an
ethernet card that allows me to connect it to the DSL modem I connect to
the outside world with. I have loaded two software packages via CD ROM
disks. One is the driver to run HP 600 series Officejet print, fax,
scanner. Without this software the Windows NT software package that came
with the computer will not print in color. Nice feature huh? Also I have
loaded EZNEC. Some things have been downloaded from the net, netscape,
some instant messengers, real player. That kind of thing. When the
computer has locked up none of those programs (except netscape) were in
use, though I cannot say that they were not running, I admit that I do
not really know how to tell for sure what is "running" or "loaded" or
whatever. So my question is, given all of the above, what is you best
guess as to what causes this system to occasionally lock up?
Still not ready for takeoff, even with a parachute.
