I have a fairly small wxPython app which I’m just getting back to after not touching it for a year or so. It’s been running fine (apparently) under Win98 and WinNT, and appears to run fine under Win2K.
But, I just started playing with Boa Constructor; not using any of the widgets, just using it as a debugging editor. When I exit the application from any of the “preliminary” screens, I get no error. However the “normal” finish for the application presents a simple dialog with an “OK” button. Code is as follows:
MsgText = "Goodbye!"
dlg = wxMessageDialog(self, MsgText, 'Logout Successful', wxOK | wxICON_INFORMATION)
dlg.ShowModal()
dlg.Destroy()
sys.exit()
Clicking the button appears to close the app but generates the error text in Boa, which I’m afraid I don’t begin to understand, and leaves some remnant running which I have to kill to shut down Win2K. Any help greatly appreciated.
