I tested that scenario (extra .lrp's in the floppy leaf.cfg compared to the CD-ROM leaf.cfg) and it worked, plus there are extra messages in the new code (with VERBOSE=1) which confirm where leaf.cfg was found. To be honest it didn't work at my first (or second) attempt - it was reading leaf.cfg from the floppy *then also* from the CD-ROM, re-setting the value of LEAFCFG. That is why I am confident the behaviour is correct now. dMb ------------------------------------------------------------------------------ The Next 800 Companies to Lead America's Growth: New Video Whitepaper David G.
