I chatted with Christian Shormann today after the Sketchflow session (which was awesome) about our memory leak problems. Christian is the Dirctor of Program Management for Expression. When I described our problem of many Blend3 crashes throughout the day he smiled big with the recognition of someone who had been asked this question many times 🙂 The Expression team is aware of this problem and have a fix in place in the Blend 4 Beta. Great news for our team. We have a very large Enterprise level Sketchflow project. Looking forward to installing this when I return. Theres also a patch in place for Blend 3 to fix this if I understood him correctly. Great news!
