That seems like an injection problem then.
Haz informed us a little while back that dual client uses a different injection method than decal does.
May want to pm Hazradi and ask him to take a look at this thread.
Edit: Don't think it'll make a difference, but try updating your video drivers. They are almost a year old.
Also, you could just use the built in looter with vtank and cut alinco out altogether.
