--user s3c70r , even if in the properties I have "Add to workername" checked, it doesn't pass the workername to command line.

We should read --user s3c70r.Rig02

Miningpoolhub doesnt allow connections without a login followed by a workername. ( login.Workername )

I have a s3c70r.Rig01 defined globally in the profit switching section of options to work around the bug.

Please fix ASAP.
