25695 - [PP, Dogfood/PDT+] mac: certain windows are blank when initially opened

Status: VERIFIED FIXED

(SeaMonkey :: Preferences, defect, P1)

Description

[Sosting]

Opening the preferences dialog in the 1.29.2000 Macintosh nightly build 
results in the preferences window opening, but nothing being drawn into it. A 
first attempt at clicking on the window produced an error of Type 2, crashing 
Mozilla. A second attempt caused my Mac to lock up completely.
	I have not tested this on any other platforms (no access), but I know this 
wasn't happening in the M13 final build.

Still present in 1.31.2000 build for Mac. Now it crashes immediately after 
opening the Preferences window, and tries to draw a bomb dialog (though the area 
where the dialog would appear is just a white box).

added platform parity to summary. yeah, am looking at the 2000-01-31-11 comm
bits on my G3 running 9.0, and the prefs dialog is just blank. this is a testing
blocker. alas, the macsbug stack trace i get seems useless (will attach soon)...

Matt, is this happening for you?

This sounds a bit like another crasher we're seeing when bringing up the compose 
window, bug 25948.

new info from shrirang: if he clicks around the blank window --ie, specifically
near where the OK or Cancel buttons would be-- he's able to dismiss the prefs
dialog. so, this isn't a crasher even tho' prefs are unusable... [updated
summary to reflect this]

weird . This is not happening to me on windows.
On mac yes.  Ben is this something you might have changed?
More likely the same as the bug that is same as the 
composer bug.

also noticed this occurring when i open up the Wallet Contents dialog (from
Tasks > My Wallet > Wallet Contents...).

i've not touched these files recently... could it be related to the other dialog 
problems we were experiencing today?

this is really bizarre, but the File Open dialog also appears blank when i open
it for the first time during a session. i wouldn't think this would occur with a
native dialog --adding law to cc list to see if he might have further thoughts.

forgot to note earlier, that another "workaround" for this problem is to retry
opening the Prefs, Wallet Contents or Open File dialogs...

This looks like a view manager problem, or something similar, and also happens 
with the compose window under some circumstances (bug 25962).

*** Bug 25962 has been marked as a duplicate of this bug. ***

danm might want to know about this, since it could be related to event handling 
in dialogs/windows.

This is caused by the fix for 6553

put on beta1 and PDT+ radar.

Comment 17

[Simon Fraser [no longer active]]

Now that I backed out the change in 6553, this bug should be fixed.

Comment 18

Fixed

Bulk moving Pref UI bugs to new component Preferences.
