clean histroy selected items don't work

[andreas]

hi everybody,

i'm using v1.1b9 but still have the following problem:

i want to delete the history of a selected item under configuration - items - smtp (i.e.). i click the checkbox and the the button "clean history selected items" but the values stored for smtp are still there. (i check the values under configuration - triggers - expression of the smtp trigger.)

what have i done wrong? how can i delete the history of some items?

"Clean history selected items" and "Clean history" buttons don't work for my in configuration of items.
