answering prompts with Yes doesn't seem to work
 

Hello,

I am currently using the command line options -I-Y to answer yes to any prompts, and yet in my log file a prompt is answered with 'N', and my script fails.

I realise this may be more a VSS issue, but if anyone has encountered this and can offer information, I would be most appreciative.

Thanks...

I haven't encountered that, but it does appear to be a SourceSafe issue (the SourceSafe action invokes the VSS command-line executable to actually perform a SourceSafe operation). You can check the 'Log command-line...' option on the Advanced tab, rebuild and include the ss.exe command-line when contacting MS support.
