very weird -- I don't see anything wring with that code. Could you 
describe the symptoms again?

Also, just for the heck of it, try doing the same thing, but loading the 
bitmap from a file, instead of drawing it.

And make sure this is the code you're running:

#!/usr/bin/env python

import wx

class MyFrame(wx.Frame):
     def __init__(self, parent = None, id = -1, pos = (10,10), title = 
"HelloWorld", size = (800,600)):
         wx.Frame.__init__(self, parent,id,title, pos, size)
         self.pnl = wx.Panel(self)
         self.pnl.SetBackgroundColour("blue")
         self.btn1 = wx.BitmapButton(self.pnl, pos = (50,50), 
size=(300,400))
         self.buffer = wx.EmptyBitmap(300,400)
         dc = wx.MemoryDC()
         dc.SelectObject(self.buffer)
         dc.SetPen(wx.Pen("green",1))
         dc.Clear()
         dc.DrawLine(1,1,200,200)
         self.btn1.SetBitmapLabel(self.buffer)

class App(wx.App):
     def OnInit(self):
         self.frame = MyFrame()
         self.frame.Show()
         self.SetTopWindow(self.frame)
         return True

def main():
     app = App(False)
     app.MainLoop()

if __name__ == '__main__':
     main()
