Issue with deleting in linq?

[i00]

If I add an entry to something bound with linq then delete it before having committed anything I get the following error:

System.InvalidOperationException (System.Data.Linq.dll) - Additional information: Cannot remove an entity that has not been attached.

I searched on the internet and all of the stuff I found said to place an .Attach(DataObject), which made it work! .... kind of ...

Now adding and then deleting the item right away works, but now when I try to delete an existing Item I get:

System.InvalidOperationException (System.Data.Linq.dll) - Additional information: Cannot attach an entity that already exists.

Do I need to somehow see if the item was attached and if not call .Attach?

Any ideas? ...
Thanks in advance,
Kris

I just found this post:

That checks it ... is this the best method?

Thanks
