Trim Chars with NET-PC 5

hi we are working with unix informix-db-server and win 3.x clients with informix-net-pc 5.01 and powerbuilder-gui-tool as frontend. connection powerbuilder - informix-net-pc via odbc is no problem, everthing works fine. connection powerbuilder - informix-net-pc directly via inbuild-powerbuilder-driver doesn't work very well. 1. no triming of char-columns (informix space terminated string problem) 2. sync-problems between powerbuilder an informix-net-pc. Example: powerbuilder terminates, informix-net-pc and the server-sqlexec-process are still at work, terminating a bit later with stack-error at isqli501.dll. are there any solutions, informix-net-patches or ... bye
