(I'm back - been off WB for a long time now - but still dabble in it)
This is OT, but I've often asked general Windows questions here in the past and gotten good answers (better than I get from any of the usual online help places).
Another Win7 thingie. Say I have a network drive (which is actually a Samba location on a Linux machine) mapped to, say, W: in Windows. I have a file on there called, say, foobar.jpg. I can read, copy, or delete that file from Windows - no problem. But I cannot run it. I would like to run it and have it come up in whatever photo viewer is the default.
When I run it (directly from the CMD prompt), I get "Access denied" (also if I run it from a WB script via any of the Run*() functions). If I copy it to a local drive and run that, it of course works as expected. Why is this and is there a workaround?
Not sure if it is the issue in your case but Windows 7 was notorious for a buggy SMB protocol implementation.
