However, we have also found that some news servers are very slow to return the complete message list. What to Purge dialog. This will make Agent work the way it used to. If you have the group sorted by anything except Thread, Agent has to sort it into Thread order, update it with the new headers, and then re-sort it back into your original order. On some systems this can take a considerable time, especially with large newsgroups.
Agent now keeps track of ranges of retrieved messages instead of only the highest message retrieved.
This fixes the problem experienced by many Demon users, where Agent was not retrieving all messages due to non-sequential message IDs on the news server. Before, I could decrement the highest message retrieved number and then get new headers. This option controls whether Agent records gaps in the retrieved message range. If Agent's list of retrieved messages contains gaps, Agent will always check for messages in the gaps when retrieving new headers. This option simply controls whether Agent records the gaps.
