I'm guessing: svn.exe is trying to write to stdout, but its output buffer is
full, so it waits. Then, you cancel the batch job, so any pending output is
discarded but at least it allows svn.exe to continue running.

While waiting for the process to finish, you need to pump its output to the
log already.

BTW, you are discarding any output to stderr, I think. Try using

  svn.exe ... 2>&1

for the commandline or mabe use objExecObject.StdErr (if that exists, I don't
actually know wscript).

Good luck!

I'll try that Uli, thanks
