I disabled error reporting, Thank you. We will see if this helps.Can the dwwin.exe be removed (and backed up somewhere? safely?- Thanks- Terry Mathis.Sounds like this should be a FF code writing fix also.

Depends what the location of the file is. If it's NOT \windows\system32\dwwin.exe it is probably spyware. Lots of spyware files are disguised as apparently legitimate windows files.
C:\windows\system32\dwwin.exe is another application than C:\WINDOWS\dwwin.exe or  C:\Program Files\dwwin.exe.

I am a Systems Security Analyst, my machine is ultra well protected, updated, and scanned frequently. Avast Pro, Black Ice, SpywareBlaster, SB Search and Destroy, Spyware Guard, a-squared, plus a few other goodies..dwwin.exe is where it is supposed to be.

Still pointing at FF 1.07 Coding problem?

Thanks for the input

reporter: please reinstall firefox and be sure to include talkback. then, hopefully when you crash, you'll get a series of dialogs from talkback, include your email address (it'll help people find your reports), then run talkback.exe and copy the incident id to this bug.

- Already done, used workaround from reply #1, but still that won't fix the coding issue,so far dissing 'Error Reporting' AND in service.msc was a 'dirty fix'..I doubt that the crashes will continue.

FF Coding?

Thanks for all!- Terry

INVALID; not a Firefox bug.

dwwin just means we crashed, but w/o a stack there's nothing we can do about it. when you dismiss their error reporter, the os of course closes us because we *crashed*. you can either get the .dmp file listed in the error report and analyze it w/ windbg, or attach w/ windbg directly and analyze the process crash directly.

but dwwin causing the browser to close is not a bug, it's by design.
note that there's only one *instance* of firefox, all windows share a common instance. this is also by design.
