In my app I use todbc(),
it worked fine until yesterday, but today get this error:

this is the source
oOdbc := TOdbc():New( cDSN, cName, cPass )

oOdbc:ShowErrorList("ODBC session not successfully initialized, aborting...")
oOdbc:End()

what happens?
if I put the tdbodbcd.prg source file in my directory and compile the tdbodbcd.obj file in my .exe then it's all ok!
why?
