* TITLE/SUMMARY Complex forms in tables result in several minute freeze when viewing page * STEPS TO REPRODUCE 0) Launch Apprunner 1) View http://www.prometheus-music.com/gecko/wire4a.html 2) View http://www.prometheus-music.com/gecko/wire4b.html *** 3) View http://www.prometheus-music.com/gecko/wire4c.html (...both of which are derived from wire.ap.org.) * RESULT - What happened Upon viewing 4a, an approximately 5 second pause takes place before each of the four form pop-up menus draw. Upon viewing 4b, an approximately 2 minute pause takes place before anything is drawn. (wire4b.html is the same page as 4a, but with the table that contained the popup removed.) Upon viewing 4c, an approximately seven second pause takes place before the single pop-up menu is drawn. (Wire 4c is the same page as 4a, but with three of the four complicated forms removed.) --> During this pause, the application is quite frozen; can't move or resize window, and menu bar generally doesn't respond. <-- (The actual wire.ap.org page exhibits other problems on Seamonkey, specifically, the images don't display upon finally being drawn. However, I'm assuming that this is probably a side-effect of this bug, and not documenting separately.) - What was expected Page to draw within several seconds upon opening URL. * REGRESSION - Occurs

Beauty test cases, Eli. This sounds very much like bug #4387. See the discussion there between troy and pollman (who apparently has just checked in a fix). Dup?

(That's high praise coming from Mr. John "Give me 10 pages of incomprehensible HTML and I'll give you a clear test case in 10 tags or less" Morrison. ;) But, yeah, I agree; this is probably one of a bunch of duplicates of 4387. (Will confirm that it's fixed in the same build that 4387 is fixed.)

I checked in a fix for 4387 and it's kin yesterday. Here's my timings of the pages before and after the fix. It's on a Pentium 166MHz 64 MB RAM, Windows NT 4.0. Pages were mirrored locally to eliminate DNS and traffic effects. wire4a.html 98 sec. before -> <1 sec. after wire4b.html 15 sec. before -> <1 sec. after wire4c.html 6 sec. before -> <1 sec. after The fix was checked in sometime around 5PM 08-Apr-1999, so any build after that should be OK. (I tried on Linux and the times were closer to the 10 second range on a PII 266 128MB after the fix, but still a vast improvement over yesterday.) *** This bug has been marked as a duplicate of 4387 ***
