damn, what happened to all my text!

argh.

rh 6.1, running gnome.  working on getting a stack trace now.

this may not be an xserver hang.

but, I tried this:

click on a message, don't release the click until you are over the folder (it
doesn't seem to move the message) but it doesn't hang and the pointer returns
from a drag and drop pointer to the normal one.

now, try this:

click on a message, start a drag an drop, and let go of the button when you are
still over the thread page.  the pointer never returns to a normal pointer until
I quit mozilla, and that is hard to do in that state.

I think esther has seen this too.

hmm, you have to work at getting this to happen.

sometimes a drag and drop (back on to the thread pane) doesn't cause the
problem, some times it does.

it took me a few tries to get into that nasty state.

I've seen that too, but couldn't figure out how to reproduce it.

Comment 5

[Christopher Blizzard (:blizzard)]

Yep, that looks like my bug.

Comment 6

[lchiang]

I'm nominating for beta1 since this is a pretty bad system hang.

Comment 7

[Phil Peterson]

PDT+ since it sounds serious. rickg wonders if this is a Gnome bug we won't be 
able to fix.

Comment 8

I mentioned gnome so that blizzard would know what wm I was using.

It may not matter.

Comment 9

[Christopher Blizzard (:blizzard)]

It doesn't have anything to do with gnome.  ( We're not linking with gnome. )
I'm pretty sure I can guess where it would happen in the code.  I've seen it
happen before.

I can now consistently reproduce this by selecting a message, and then click,
drag, and let go of another message within the time it takes to load and display
the first message.  When the message is loaded I have the right-angle cursor and
can't bring another window to the foreground or alt-tab away from Mozilla.  This
on Linux build 2000.02.19.09.

Putting on PDT- radar, will relnote for beta1.  lchiang, please add text for 
this relnote to:
http://bugzilla.mozilla.org/show_bug.cgi?id=25524

[lchiang]

this is pretty bad and can be done accidentally. It locks up the entire system!

Comment 13

[Alec Flett]

removing PDT- so PDT can reevaluate.. this is critical, and as lisa said in the
last comment, this locks up the entire system, not just seamonkey.

Comment 14

[Richard Zach]

This doesn't hang the X server--if I switch to virtual terminal using Ctrl-Alt-1
and do "killall -9 mozilla-bin", everything's back to normal.  What happens is
that you can get yourself in a state where Mozilla thinks you're holding down
the mouse button when you're actually not.  And in the middle of a drag-and-drop
operation, you also can't Alt-Tab to another window.  Somewhere the MouseUp
event gets lost.  Maybe this is an event handling problem?  Has anyone tried my
Rx from 2-19 on Windows or Mac?

Comment 15

Linux folks would know what they are doing.  Please put text for relnote 
workaround in http://bugzilla.mozilla.org/show_bug.cgi?id=25524

Moving [PDT-] from Summary to Status Whiteboard

this is a nasty bug, as others have stated.  is d&d working in other places
(like bookmarks?) on linux?

if not, could we stop the bug for beta by turning off d&d on linux?

Comment 18

[Stuart Parmenter]

I have a fix.  trying to hunt down someone to approve.

Comment 19

[Christopher Blizzard (:blizzard)]

I can review.  What's the fix?

Comment 20

[Stuart Parmenter]

fix checked in... blizzard - this is a brute force fix and could be fixed in a
better way i'm sure.

Comment 21

[Christopher Blizzard (:blizzard)]

This isn't the proper way to fix this.  I'm leaving it assigned to me to fix the
right way.

Comment 22

[Christopher Blizzard (:blizzard)]

Reassigning to me...

Comment 23

[Christopher Blizzard (:blizzard)]

Ok, a real fix for this has been checked in.

Comment 24

[Richard Zach]

I tried and tried and couldn't get it to hang. So I'm marking it verified.
