mozilla won't start

[peter]

I've searched the archives and have seen this problem raised before, 
but can't find an answer to it there, so here goes... I'm having 
trouble with mozilla; it just won't run. When invoke it from the 
command line, either by using the command mozilla, mozilla-bin, 
run-mozilla.sh, all of those run with the full path prepended and about 
a zillion (give or take) variations, i just get nothing. well, not  
*quite* nothing. when i run mozilla -splash, i get the mozilla splash 
screen, *then* i get nothing. :-) no errors at the command line, no 
core dumps, and nothing in any log files that i can find. i've tried 
erasing and reinstalling the packages using yum, nodice. i've tried 
installing newer versions of mozilla (like the 1.7a version that was 
mentioned in another recent thread), and that doesn't even give me the 
splash screen like the yum-provided package does. ideas? suggestions?
thanks,
peter
