Hi All,

New here, just getting to grips with PP so please bear with me if I ask daft questions!

I've for a simple pipeline with a form on it that requires the user to upload 4 files:

Each one needs to be passed on to the work pipeline against a specific parameter.  It's all working fine, server paths are passed to the worker but it all goes wrong when it's run a second time with input files already existing on the PP server.  First upload gets:

This seems to work, the second chooser shows:

and then, after clicking Overwrite:

clicking Overwrtite at this point causes it to hang without doing anything further, Cancel doesn't work either!

This won't be a massive problem when the worker runs to completion as that will tidy-up these files however it will completely break if te user uploads the files and the restarts before submiting the form.  I've attached a pipeline that demonstrates the issue if you upload four files to it, refresh the page and try again.

Cheers,

Iain
