[reportlab-users] pdfgen creates corrupted pdf files

Hi all,
I'm programming an app using wxWidgets and VC++ 6.0 on windows.
To produce reports and documents I use the platypus engine. To run the reports 
I use the python C++ api linked into the app.

Everything works fine just until I try use some Microsoft stuff :-((
What I do is to generate a pdf and then mail it using simple Mapi 
(MAPI32.dll). The mapi is not called from pyhton but directly from C++.
The problem:
Before the first call to the mapi the app generates pdfs without any problems. 
After calling the mapi once pdfgen still generates pdf-files but they are 
corrupted. Unreadeable with Acrobat on Windows and LINUX and with KGostview.
I checked the contents with an Editor. At first sight the corrupte files seem 
to be ok.
But there are some differences. Example
File ok:
<< /Contents 8 0 R
 /MediaBox [ 0
  841.8898 ]
 /Parent 7 0 R
File corrupted:
<< /Contents 8 0 R
 /MediaBox [ 0
  841,8898 ]
 /Parent 7 0 R
As one can see the decimal paper size (I believe) numbers have changed the 
decimal point representation from "." to ",".
And the binary data streamis somewhat different in size an looks totally 
different due to encoding.
There are no error messages like tracebacks in the logfile I use. The Current 
locale (german) seems not to be chagend by the mapi calls because all forms 
work well before and after.
The behaviour is not report depent. All reports fail after a mapi call.
And its the same with 1.19 and 1.20.

Any hints would be very appreciated!
