tpdsql version 2.2 was working but now the gui window opens and then
immediately closes.

The tdpsql.log file show the request QUERY SQL but there is no connection to
the TSM 4.1.3.0 Server running on AIX 4.3.3 ML06 and there is no entry in
the dsierror.log file.  A command line tdpsqlc QUERY SQL gets the same
results.  However, a tdpsqlc QUERY TSM * /all does list the backups.

Any suggestions as to what would cause this?
