Thanks for the reply. I initially thought it was perhaps just my hardware but I've since tested this on a 11_RC6/i386 VM with the stock /etc/ttys settings and I get the same back color erase issue with TERM=wsvt25 so my guess is something changed between 10.x and 11.x that may only affect the i386 port. I've be trying to find other CLI programs that might also make use of this back color erase feature; so far apps like links (similar to lynx) and the native worms(6) game don't show any issues. -b
