Description

[Mike Pinkerton (not reading bugmail)]

- go to http://quote.netscape.com/quote/Quote.tibco?symbols=hwp&view=quote

while the page is loading, the stock chart is in the correct position and
visible. As soon as the throbber stops animating, the stock chart vanishes.
There is no way to get it back.

branch, 10/31/00-14 FC build.

I see this on other pages, just this one is very reproduceable. This appears to
be mac only.

Comment 2

[Mike Pinkerton (not reading bugmail)]

cc'ing mac folks and karnaze for tables. this could be a table reflow bug.

Comment 3

[Simon Fraser [no longer active]]

I see this too. Maybe it's a caching thing?

Comment 4

[Simon Fraser [no longer active]]

I'm seeing this same bug on my.netscape pages, where ad banners (gasp!) are 
disappearing at the end of page load.

Comment 5

Reload this page a bunch of times:
<http://my.netscape.com/mynsnews/story.tmpl?table=n&cat=50900&id=
200011020729000235815>

About 10% of the time, the ad banner at the top will disappear.

the ad example on netcenter is using the following HTML for the ad banner (see 
from a traffic sniffer):

>000009C2> <!-- START: AOL 468 X 60 HTML AD TOKEN: DO NOT EDIT OR

Which sends off this query:

Maybe this is a document.write thing?

Comment 7

[Mike Pinkerton (not reading bugmail)]

what about for the stock chart on the netcenter quote page?

Comment 8

[pnunn]

Could we call disappearing ads a feature?
:-b
-p

Comment 9

[pnunn]

I just checked this on a linux build and the page looks ok.
I could believe the imgcache was a culprit if it occurred
on other platforms too. The fact it only shows up (or not show
up) on the mac points more to platform specific code, like
rendering. Sounds like a paint is going awry.

adding Patrick as he likes this kind of bug.

Reassigning to Kevin for a mac gfx check.

Marking rtm-. Not enough time left to fix for rtm.

Comment 12

[Kevin McCluskey (gone)]

Waqar can you take a look at this on the Mac and see if its still a problem?

Comment 13

[waqar]

Investigating.

Comment 14

[Mike Pinkerton (not reading bugmail)]

hrm, this url no longer seems to be a problem (1/19/01 build). i hestitate to
close this bug though since i'm sure i've seen this in other places

Comment 15

[Mike Pinkerton (not reading bugmail)]

this happends on the 1/31/01 build on

http://quote.netscape.com/quote/Quote.tibco?view=quote&symbols=AOL

so it _does_ still happen. I've also seen this on a bunch of other pages with
this build on my powerbook.

Any ETA?

See also bug 63091 and bug 66508

Comment 17

[hirata masakazu]

To clarify the timeline, this bug was filed before NS6 release.
Bug 63091 started after NS6 release in Trunk builds around 12-15 and persisted
until 0122 build as far as I can confirm, and 0122 build does not show this
particular problem at the URL above.
Bug 66508 started in 0124 build.

Comment 18

[hirata masakazu]

The fix for bug 66508 seem to have fixed this, too.
Considering the time line, which actually originates in bug 56170, I guess this
can be closed as a dupe to 66508.
