disappearing bands

When I visualize PCR products on agarose gels (0.5x TAE,  ethidium 
bromide),  about 1 out of 10-15 of the gels has no bands, not even 
the DNA marker ladder bands.  If I re-do the gel from scratch, 
usually it looks OK (I get the expected bands).  Probably something 
really stupid is going on, but I am baffled.  Anyone else have this 
kind of dumb problem?
