What steps will reproduce the problem?
1. Download Google App Engine
2. Download, install Rpyc and properly configure project and remote engine
3. Try to Debug

What is the expected output? What do you see instead?

The server hang.

What version of the product are you using? On what operating system?

Pyscripter on vista, App Engine Preview

Please provide any additional information below.

I attach the entire project, the only thing you need to reproduce the 
enviroment is the google app engine in your path. To start the I used a project with ad hoc configuration. 

Google app engine is a new framework to develop application that can run 
on google server, it' hot ;-), can you supply a guide to use pyscipter to 
debug in this enviroment ?

PS: your editor rocks!

I can't figure out if it's really slow, or hung.  Google's code tries to reload all 
modules (except encodings), so I extended it to leave Rpyc alone too and that seems 
to help.  At one point I had to tell it to leave bdb alone too, otherwise it would

I get the same experience as Enrico, using Windows XP, with PyScripter

I can run the Hello World example while the PyScripter run with

When PyScripter is closed (in effect killing the run), the Hello World server is no
longer available.

The above is true with the Internal Python Engine.  I'll try it with the Remote Engine.

The run produces:
*** Remote Python engine is active ***
Command Line : -d helloworld

localhost:8080 on Firefox gives no result for about 30 seconds and then pythonw takes
50% of the cpu time - still no response to Firefox  (Dual core CPU)

I'll look into the PIL problem.

PyScripter must be closed to terminate the run.

I can verify that this is indeed a problem with PyScripter.

There is one way to work around the issue though, that is by placing a break point at 
the But to get it working you need to input http://localhost:8080 a 
few times. And then your output will show on your web browser. You still can't step 
into your code to debug, as explained in here 
pyscripter) and as what I have experienced.
