You might be running into problems with duelling message pumps in the
GUI loops.  The 'os.system' call runs in a subprocess, not in an
independent one.

If you use 'subprocess.Popen', you can explicitly wait on the second
process, which will hang your first GUI, but may cause the second one
to run better.  Or, you have the option to not wait for it.

I see that 'os.system' waits for the second process to complete, while
'startfile' does not.

Just a thought, are you looking for the 'webbrowser' module?


Another option is to run it from a separate thread.
