automatic index rebuild broken?..

it seems that the index of my project isn’t rebuilt automatically anymore.
when i remove a todo, is remains in the tasklist, until i manually rebuild the index
or when i search for text, i end up on the wrong line’s (in files edited after the last manual index rebuild.)

(using M2M studio 1.1.1)

oh, and i checked the automatic rebuild setting, and they seem to be correct.

These features are part of the standard Eclipse/CDT implementation… It’s true that sometimes we noticed such a “bad synchronized” behaviour.
Does it still occur even after a M2M Studio restart?
