Grails 2.5, Java 7 64bit, windows 8.1

This is very odd. We have a large app, and I am the only windows user (everyone else on macs). For some reason, I cannot do anything with environments on the command line.

E.g. I can do this:

```
grails run-app

```

But I cannot do this:

```
grails -Dgrails.env=myenv run-app

```

It always says:

Script 'Myenv' not found, did you mean...

In my DataSource.groovy, I have:

```
 environments {
     development {
        dataSource {
        // stuff
     }
     myenv {
       // same stuff as the above stuff
     }
 }

```

It works for other users, just not me.

Any ideas how I debug this? It means I have not been able to do development, as I need multiple envs to do liquibase diffs etc.
