Dear folks: I posted earlier today about a problem where the left and top border of a table initially rendered when the page was rendered, and then disappeared after the page was completely loaded into the browser.
(Yes, the page does validate, by the way.) I continued to try to understand the problem and tried to reproduce it in other contexts, and I now think it has something to do with the number of rows in or the vertical height of the table as a whole. The table containing the images is created by a php include that loops through a directory full of images; the directory is updated with a new image every half hour or so. The directory contains as many as around 100 images, but is cleared every couple of days, so it never gets really large. Thus the number of rows in the table can vary, depending on how far into the week we are. When I was testing different versions of the page, I found that a table w/ a header and 65 rows of images renders correctly: See: http://www.star.nesdis.noaa.gov/smcd/emb/ff/draft/HE_CONUS_inst65.php But, if the table contained 66 rows + header, the top and left border of the table started to render when the page loaded, then seemed to disappear. However, if you scroll down a bit (how much you need to scroll varies), the left border reappears, then disappears again before the end of the table. Please note -- I just posted the above test pages to an internal server, so they won't be visible on the external server until after 6:30 p.m. EST or so. (refresh schedule) I am baffled. Any insights are welcome. Thanks.
