Hi support

 I am not sure if you know about this issue.

I am running pgplus 8.3.3 version under Centos and pgadmin 1.8.4 win32 version in windows xp . While tring to do a backup from windows machine it complain about version mismatched and tells me if I want to proceed the backup use -i option.

If possible, pls email me the solution.
