Python script running slower in PyScripter than with IDLE

Up until recently we used the IDLE interface to write and then run Python scripts for ArcGIS. I had PyScripter (PyScripter v2.5.3 32-bit version) installed on my workstation which is a Windows7 64-bit machine. I am running ArcGIS 10.0 SP3 and the Python version is 32-bit; below is the first line when opening the IDLE program that came with the ArcGIS installation.
Python 2.6.5 (r265:79096, Mar 19 2010, 21:48:26) [MSC v.1500 32 bit (Intel)] on win32

Post installation I noticed several versions of PyScripter IDE to choose from in the Start menu: PyScripter for Python 2.4 thru 3.3, and also one for 'Latest Version'. I assumed that the 2.6 version was the best one to use as from the above message in IDLE, it seems our Python version is 2.6.5. I have noticed that when running Python scripts from inside PyScripter they run much slower (5 times slower) than when running the same program from either a DOS command prompt or the IDLE program.

Any thought as to why this may be occurring?
