replying in this manner. I am on AOL( some call it AOHell) and it is very
difercult for me to write to the list with HTML. And if thats not enought I
installed Norton SysterWorks on my PC last week and it has been jumping off
the internet every 2 or 3 minutes, as slow as I type thats not good.What did
I do wrong? Help! I will get back on that 25B800 tomorrow and let youall know
what happen . Jeff I do have a first name. The G on GOW is for Grady. You may
call me whatever you like. Thanks Again , GOW TV Service In a message dated
