Bread-Bakers v098.n056.2

I've been getting fabulous results from my bread machine and can't live 
long enough to use all the recipes I've collected.  The only problem is 
slicing the bread!  Don't tell me to wait until it cools -- i'm doing 
that.  I bought one of those knives with the guide thingie on it, but it's 
difficult to make it stay vertically straight.  
Has anyone else had trouble slicing their bread?  Any helpful suggestions?
Thanks!
