Logon script not run for second instance of user

i've set terminal server on windows server 2008 allow users log in multiple times. i've used group policy set logon script @ domain level log terminal server logons, , @ organisational unit in have users start particular programs @ logon based on terminal's name.

i'm using wyse s10 , old termtek thin client testing. when user aaa logs in on wyse, login logged , appropriate programs terminal start. when simultaneously log aaa onto termtek, login neither logged nor programs start. if log aaa of termtek , log user bbb in, login logged, , appropriate programs termtek started.

i've tried logging aaa in on termtek first, works, , onto wyse second (which doesn't work).

any ideas?

the system i'm implementing shop floor data collection system, , having use seperate logins not appropriate.
