Similar to what I was seeing with AmiIRC:
https://forum.amiga.org/index.php?topic=75048.msg851467#msg851467As suggested in above thread I'm using stackattack for now which is alleviating the MUI stack request issue but don't like to put patches in the system as much as possible. Would be nice to have something done better in this regard (can Poseidon 4.5 be updated to support MUI > 3.8 by adding option to increase stack or can MUI suppress this warning?)
