I installed pgAdmin 1.6.3 on Windows XP Czech version
After I could log in to the database, the program displayed the message it cannot write the file "c:\Documents and Settings\linhart1\Data aplikací\postgresql\pgpass.conf" (The "application data" directory is localized to "data aplikací" on czech windows) And after I confirmed this message, the program crashed. The given file and not even the directory c:\Documents and Settings\linhart1\Data aplikací\postgresql existed. After I created the directory only, it did not helped, but after I created the file itself c:\Documents and Settings\linhart1\Data aplikací\postgresql\pgpass.conf with one comment line the bug did not appeared. This is not a terrible bug, but it could be problem for some less skilled windows users... With best regards Archie
