Hang time after quick close

[Christopher Pax]

After I click the execute button and quickly click close, the program hangs.

Answer:
This Problem is due to threading. I use threading to display a string of text one line at a time over a period of time in the status bar. To do this I open another thread. When you go to close the program the thread is still running, and so it waits till its destroyed.

After spending some time reading the threading module python docs. I used the fallowing, self found solution.
from * import threading
...
listOfOpenThreads = enumerate()
for thisThread in listOfOpenThreads:
  print dir(thisThread) # this displays all the compoentents of the object "thisThread" this is what i used to find the thread stop function
  try:
   thisThread._Thread__stop()
  except:
   pass
