This problem is known to centericq's author. I once started to write a patch for it, but stopped working on it as I found out the original author is not interested. The problem explanation is easy: centericq shows old RSS news items whenever the RSS feed applies changes to older articles. Let's take the following example: centericq already showed the following items (newest last): 1. #1 2. #2 3. #3 4. #4 5. #5 Now, the new recevied RSS feed looks like this: 1. #3 2. #4 3. #5a (a modified #5, for example, #5 (UPDATE)!) 4. #6 5. #7 6. #8 Now, centericq processes the new items as follows: It takes the newest one (#8) and adds it into the message list if that one has not been shown yet, that is, it is not on top of the already added items (which is #5). ONLY that single one is tested. Thus, #8 is added. Now, it takes #7, and addes that one, as well as #6. Now, #5a is investigated. As that one is not on top of the already shown items, #5a is added, too. This even happens if #5a and #5 only differ by blanks. Unfortunately, as centericq does not recognize #5a as already shown, it tests #4. As #4 is not on top of the already shown items, it is added, too, as well as #3. A fix is rather easy: centericq would have to check every item if that one is already in the list of shown items. For this, it would not need to check against every already shown item, as only the top X (with X being the number of new items) is of importance. Regards, Spiro. -- Spiro R.
