Hi GeoKM, no, I have never tried RunInUAE so I cannot tell what is the problem here.
Flower Pot was built according to general best practice of emulating OS4.1. That means Flower Pot doesn't contain any undocumented feature, it's more or less a well configured WinUAE with few extra OS4 programs wrapped in automated installer with graphical launcher on top
So what you can do to improve the emulation is to replace WinUAE with newer one (http://eab.abime.net/forumdisplay.php?f=5) and/or experiment with its configuration and/or tweak OS4. Or if you believe the crash doesn't happen on real thing, please send a bugreport to Toni Wilen, the developer of WinUAE. The OS4 emulation (compared to OS3.x one) is still in progress.
