Hi again Jim.
Finally I found the reason !
On Vista, when computer is set to apply DEP to all programs and services the TWAINDSM.DLL crash the calling application on a MSG_OPENDS request.
I was able to reproduce the problem on all my Vista computers.
A solution is to switch the DEP for Windows programs & services only (the default configuration I think):
# Click Start, click Run, type sysdm.cpl, and then click OK.
# Click the Advanced tab, click Performance, and then click Settings.
# In Performance Options, click the Data Execution Prevention tab, and select the first option, then apply.
I think it is a critical issue for the twaindsm.dll which should be resolved 😀 .
