Hoping someone can give me some hope for success with training my 14 week TT to stay at home on her own.  I'm into the second week of leaving her for a short time - 10-15 minutes each day. I give her a kong in her crate  plus a small cardboard box with treats in.  Up to now on playing the tape I run back she has barked and howled more or less the whole time.  She's quiet for just the time it takes her to get the treats out and eat them which only takes her a few minutes.   I always leave and return without making any fuss of her but it doesn't seem to be working . Any ideas would be gratefully received . I will just keep going with it in the hope she will eventually see that the barking etc. doesn't get her anywhere but am geting a bit impatient to see some results!

Did you first get her used to being in a different room? Praise for when she's quiet ( something you cant do if you are out :-) ) and always try to get to her when she's not making a sound and give her a treat or quietly say " good girl" then leave her again.
When this is going well, after a tiring play session, into bed with a chew then leave.

it's worth the trouble working up slowly and getting her used to separation, within the house,whilst she knows you're there.

I'm having similar problems with my nearly 14 week old flatcoat. Sometimes he's fine if I leave the room and, if he's really tired (not always possible to achieve this state), he will be happy to be left in his crate when I'm out for about an hour but mostly he howls and cries for the time I'm away. If I leave him with a stuffed Kong, it's the same - quiet while he explores and extracts treats and then wails. I've been leaving him for short periods most days for the last four weeks so I'm beginning to feel a little desperate! He always stops as soon as I come into the house so he's learned that he won't be let out whilst he's making a noise. In other ways he's doing really well and is going through the night for up to eight hours but I'm concerned that we may be moving towards separation anxiety and am very keen to sort this before it becomes too big a problem!

Radio???  Radio 2 as it has lots of talking, or local prog.  Give him/her one of your jumpers (one that you have worn so it smells of you, not a freshly washed one that smells of Persil).

try putting peanut butter or such along with treats into kong and it will last much longer as a treat

No I didn't I have to admit, today I have made a point of closing her in the kitchen if I go upstairs (usually she follows me all over) I think perhaps I was expecting too much from her .  I will stick with this method until I get quiet and then extend the time little by little.  It's going to be a slow process though I think!
Thanks for your reply.

Jacey I was leaving the tv on so she could hear the voices on there,  I am also going to experiment with classical music as have been told it can have a calming effect on dogs.

Kanelch I know how you feel! You start to feel trapped in the house and that's no good for anyone. 
My breed is particularly prone to seperation anxiety but our first tibetan terrier adapted to being left without any problem - probably because I was working part time back then and knew I had to get her trained up quickly.  Think I've been too soft with this little girl!

Thanks to everyone else for the suggestions I will try them all and see what happens
