Are you running your EasyUO instance with administrator rights? That's the kind of problem that everyone would be seeing. Vewy odd.
Edit:
Just out of giggles, I stripped out the looting portion of the quester just so I could run on a container I have in my castle on Lexia. Works fine for me. One thing though that the quester should be doing is the bag must be opened before the looter can be run. But in the status you should get something like "X items evaluated, X items looted" or something like that. If the bag you are looking into isn't open, then the number of items evaluated will be 0.
So my setup is:
1) RunUO
2) No program like UOA, Razor or UOSteam running
3) running EasyUO with admin rights.
4) CLAw and test_quester running in the same instance or EUO, but in different tabs.
With this setup, this script runs fine and loots as expected (assuming the bag/container is open) The quester automatically opens the bag though. You should make sure that for your testing, you make sure that you aren't running BMEval; not sure if that part of the script ignores IDs or not. My test shows the TM_LootInProgress sub works only as long as the script is evaluating and draging found items.
So I'm unsure what your problem is - I cannot replicate your issue. I wish you luck trying to debug it.
