Hello,

the problem might be caused by the way Windows 7 64bit handles 32bit applications and/or communication between 64bit and 32bit applications.
At home I use Windows 7 Ultimate 32 Bit and at work Windows 7 Enterprise 64bit. I'll have to check with the same database I dumped at work at home again, but it seems that there are no issues with Windows 7 32bit.
There was no problem executing the commands generated by pgAdmin from within a DOS-Window for both versions of pg_dump in Windows 7 64bit - after quoting the path because of the spaces within.
The culprit might be conhost.exe. It seems that it does a CreateFileMapping for the 9.0 version of pg_dump - even after renaming the exe.
In fact pg_dump really seems to be started several times because there are different PIDs in the logs of 'Process Monitor' although I had started pg_dump just once via pgAdmin.

Hope this helps.

Thank you very much,

Peter
