I'm using Windows 8 x64. I've downloaded the latest cgminer (3.4 at this time), but when ever I try and start it I get the error message:

```
Error opening terminal: dumb

```

I've seen various post that suggest this relates to the TERM env var and setting this does change the message to end with what ever is in TERM, but nothing I've tried fixes it. Anyone know what I need to do to get this working?
