    all this trouble from a clean install even.  my favorite was when it 
wouldn't get past a certain point in the OS and i had to reinstall.  i'm 
sure i don't have a bad install disk, and i'm hoping i don't have a bad 
computer.  i tested the media, so i know its good.  but i've had trouble 
with java; which i found out i had to set the path by editing the 
.bashrc file in my home folder, yet Azureus.jar still doesn't work and 
the jrar.jar file won't work (compress, open files,) because it won't 
find my rar program (same with gnuRAR).  i found that on the internet.  
i found that umask thing in my DUMMIES reference book for FC2, even 
though i'm using FC3.  thats twice i have found something that in my 
opinion doesn't work as  it should. 
    now i don't know, but on my monitor troubles, it could be that the 
other monitor output port isn't getting enough power, but i don't know.  
shuttles don't have much power because of the tight cramped space you 
get when you start cramming stuff inside, but i was surprised when it 
wouldn't work when i put my other agp card in and recieved the same 
results.  so now i'm thinking thats a BIOS thing.  And Lord knows i'm 
not going through that much trouble (i tried though) to make it work.
    OH!  i figured out how to configure YUM and up2date (from a posting 
here), but /then/ i figured out how to configure it so that it would 
download mozplugger, and gmplayer plugins, and make the softlinks, the 
only thing i'm wondering is if version 1.7.5 is out, why is 
mozilla-1.7.3 on the yum download list?  rhetorical question really, 
don't need an answer for it.
    i'm going to study for a test i have next week, thanks for all the 
help and feedback!  i will try to get up to a meeting, trouble is most 
of them are conflicting with something!
