User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.4b) Gecko/20030516 Mozilla Firebird/0.6 Build Identifier: Thunderbird 0.1 Milestone when the # of lines of cards displayed in the addressbook equals the number of cards in the address book, the splitter bar jitters up and down by one line ... and actually causes the text in the lines near it to jitter as well. Initially it occured when I had 13 cards, and deleted duplicate. Leaving me with 12 cards, the precise # of lines in the window. I added a junk card, and the problem went away as soon as the card was inserted ... I deleted the card and the problem recurred. I then closed the addressbook (not thunderbird). on reopening it ... the problem occured. I then resized the window ... and tried it to see if there was just something magical about the number 12 ... but this time I could fit 15 cards in ... and the problem occurred as soon as i added 3 more junk cards, and would go away as soon as I deleted a card ... I then added a card, it came back ... and the 16th card made it go away again. I resized the window back to only fit the original 12 cards ... and it did not occur on the resize ... or at any point since. I have attempted to duplicate this with different sizes, but unable to reproduce those 2 initial results. Either during the same executable session, or during future sessions Reproducible: Sometimes Steps to Reproduce: 1.as above 2. 3.
