I have a wxPython program which does some calculations and displays
the results. During these calculations if I click the mouse inside the
dialog the program locks up. If I leave the dialog alone the process
completes fine. I have tried running the function from a separate
dialog with Show Modal and I have tried using SetEvtHandlerEnabled all
to no avail. The program is long and occupies several files so I won't
show the whole thing but here is the calculation part. How do I block
events?

self.tc_angle.SetValue(ang)

self.tc_height.SetValue(float(hgt)/10.0)
self.UpdateValues()
self.Redraw()
self.DrawRays()
sPower = self.tc_power.GetValue()
Power = sPower.split('%')
TotalPower +=float(Power[0])
Counter +=1
sleep(0.1)
efficiency = TotalPower/Counter
self.tc_eff.SetLabel(str(round(efficiency,1)))
