I know of no reason why Netscape wouldn't achieve the same time saving results!!

Nor do I. I was simply stating my completely uninformed opinion that Netscape and IE running together might experience problems, caused by M$'s aversion to sharing. Two or more instances of Netscape running together is not a problem, from my own experience when I used to use 4.75. Two e-mail programmes, that is interesting. I used to use OE, but now I only use Pegasus, apart from occasionally tesing certain functions in OE to see how they work.
