Expected Results:  
left the page as it had been prior to the menu's presence

It'd be good to find out the minimal CSS and HTML that produces this (I suspect
the border-collapse plus margin on the table).

I'm seeing this using the test case with:

Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.6b) Gecko/20031216
Firebird/0.7+

(I see nothing with about:about)

I can confirm this on the latest Firebird build tested on winXP

[Alex Hirzel]

Both the testcase and about:about work as explained for me.

I tested this bug with both Mozilla nightly build of 2003-12-19, and Firebird
0.7, both running on W2k. In Mozilla [Mozilla/5.0 (Windows; U; Windows NT 5.0;
en-US; rv:1.7a) Gecko/20031219] the bugs occurs, in Firebird [Mozilla/5.0
(Windows; U; Windows NT 5.0; en-US; rv:1.5) Gecko/20031007 Firebird/0.7] it does
not.

this bug is a regression from the overflow checkin. Now that the leaking out
borders are reported as overflow the table paint code sees larger damage areas
that may not not be covered by the bc border. There is already a protectio for
this in the y- direction and this patch adds it for the x-direction. It might
be good for 1.6

This was working just fine on a trunk build a few days ago, but now I am seeing
this behaviour again on a nightly Firebird trunk build:
(Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.6) Gecko/20040118 Firebird/0.7+)

I don't have the priviledges to reopen the bug though.

Comment 12

[Alex Hirzel]

Still seing this

Mozilla/5.0 (Windows; U; Win98; en-US; rv:1.6) Gecko/20040113

Reopening as per comment #11 and my own observations.

Comment 13

[Bernd]

this hasnt been checked in any branch neither 1.6 or any fb branch use a trunk
build before reopening.
trunk builds show 1.7a+ in the build identifier
