We'll have a fixpack for dasBlog 1.6 within the next two days that will roll back a few internal changes that had been made to improve performance, but unfortunately caused significant instability. The code is already checked into our tree and we're going to have the fix packaged up for download very soon. If you don't have 1.6 installed yet, wait until we have the fix. Within a week we are going to replace the 1.6 verson available from the Gotdotnet workspace with a version that incorporates the fix.
