  Just wondering, last time I looked (when DirectShow was included with the DirectX SDK) the quartz debug dll was pre SP2, now in the Platform SDK it does not seem to exist at all.

• VICAllen Problems with state persistence and timer services

  Hi, I've experimented with adding the SQL state, timer and tracking services to the Lab1 sample step 4 (the expense report approval workflow). The tracking service works fine, but it seems that the state and timer services get the engine stuck on the ListenForManagerApproval activity.
