171915 - Crasher on alt-tab switch away from Mozilla after altering a text input field [@nsEventStateManager::PreHandleEvent]

Status: RESOLVED INVALID

(Core :: DOM: Events, defect)

Description

[Michael Hearn]

This one is a bit odd, placing in XSLT because it doesn't happen with regular
HTML pages, though it's unlikely to be an XSLT specific problem.

Basically, I transform a page from XML, have some text edits on it. All works
fine, until I add some characters to an edit box and alt-tab away from the page,
at which point both Moz and the Mfcembed program die.

A talkback entry for this is: TB11858154Q

Michael, would you please try to reproduce this one with a more recent build. I
only see a couple of incidents and all with builds on 9/10.

Might be Bug 78422 is in some way related to this here?

WFM win 2000. Sending to DOM Events for investigation

Comment 6

[Michael Hearn]

It appears to be either a regression (it works in 1.1) or my installation
somehow has become corrupted..... i'll get a nightly and try with that.

Comment 7

[Michael Hearn]

This doesn't appear for me with 1.1 or the latest nightly. There was another
such crasher, I'm beginning to think somehow my install got corrupted. Marking
invalid, sorry for the timewaste.
