I submitted this bug report at the sourceforge project.  Is this a known problem?  Any work-arounds?

Running two 'start'ed actions kills the process under ghc and ghci. Example:

import Graphics.UI.WX
main = io >> io where io = start (frame [] >> return ())

OS: Windows XP
Software versions:
ghc: 6.6
wxWidgets: 2.6.3
wxHaskell: 0.10.1
