Did not know where to post this so I'm posting here because the error "an unsupported operation was attempted" seems to happen when the New Window script step gets executed.

I was watching the script debugger and it appears, at least on the surface, that whenever I hit the NEW WINDOW command I get the error "an unsupported operation was attempted".

I'm not doing any web development - this is straight Filemaker development. I don't see any reason why this would invoke that error.

Anyone have any ideas? I'm on XP Professional. I'm leaning towards XP as the culprit.

Can you post a screenshot?

it does sound like a FM error though...

See Enclosed screen shot.

Did you resolve? This has come to plague the one XP user in our group. It cleared after a restart, so I suspect memory issues. The PC is slow and glitchy otherwise, so I suggested IT should tune it up. I'm not using the new Window command, but opening a second file.
