I have a recent build of my SYSUTILS plugin which works fine under WIN7. When I try it with the same TCC (14.03.51) on Win XP/SP3, I get this message from TCC at startup time. Code: TCC: (Sys) The specified procedure could not be found "D:\tc14\Plugins\SysUtils.dll" Rex, do you have any idea how that could happen? Is there a way I can figure out what procedure can't be found? Thanks.
