One thing I know I've read several times is that all UI interaction
with wxPython *must* be in the main thread; updates to the UI from other
threads either won't have an effect or (as I've experienced) throw errors. It
sounds like you're trying to structure it correctly, but the form is still
getting tripped up by the threads.
You might want to ask on the wxPython list, because there is nothing
that we're doing at the Dabo layer that would affect things. You might also try
the variation that wx offers: instead of:
dabo.ui.yieldUI()
try:
import wx
wx.SafeYield()
... and let me know if that make any difference.
