Here is the exception I am getting:

ntdll.dll.

This happened when I was using the libpq.dll from the official binary 
distribution of PostgreSQL 8.1.2. When I compiled libpq.dll myself to 
find out more, amazingly everything worked fine, there was no exception. 
I compiled with nls enabled and without, both works. Only the dll which 
comes with the Win installer causes the problem. Any ideas what could be 
the problem here?

As already mentioned, there is also a wrong attribute align=high and as 
I just saw, also align=left and align=right attributes without quotes.
