283452 - Cannot drag and drop received attachments from message window to Explorer in Win98

Status: RESOLVED WONTFIX

(MailNews Core :: Attachments, defect)

Description

[Gary Ruben]

User-Agent:       Mozilla/5.0 (Windows; U; Win98; en-US; rv:1.7.5) Gecko/20041107 Firefox/1.0
Build Identifier: Thunderbird version 1.0+ (20050223)

Attempting to drag and drop an attachment from a received message to Explorer in
Win98 results in an error dialog "Error moving file" Cannot move file: File
system error (1026).
This appears to be Win98 specific. I've verified this is not a problem in WinXP.

Reproducible: Always

Steps to Reproduce:
Just try to drag an attachment and drop it into a Windows Explorer folder.
Actual Results:  
Error dialog "Error moving file" Cannot move file: File system error (1026).

Expected Results:  
Copied the file to the destination.

You're using IMAP mail?  See bug 253711 -- this is probably a dupe of that one.  
The error message reported there (under WinXP) is different.  Check if the 
workaround there fixes your problem as well.

I'm using POP, but in response to this suggestion I've verified that it behaves
identically to what I described with IMAP also.

I tried the CTRL-drag workaround and it makes no difference ie. doesn't fix the
problem.

More possibly relevant information. Please excuse this if it's confusing. It is
not simple to describe.
I noticed something new in Win98:
As soon as the file being dragged is moved outside the Thunderbird window
extent, a dialog flashes up. No drop event has occurred yet - this implies a
drag-over event handler is firing when it shouldn't. For most file types, the
dialog closes immediately, too quickly to read the contents. However, with
attachments of certain types (.eml or .txt) files, a dialog titled "Saving"
appears (I'm guessing this is the same dialog in both cases) and remains visible
until the mouse button is released over a drop target, such as an explorer
folder or the Windows desktop. The attachment types seem to differ between
Content-Transfer-Encoding: 7bit (dialog remains open)
Content-Transfer-Encoding: base64 (dialog flashes up then immediately closes)
although I don't know if this is the factor affecting the dialog behaviour.
The "Saving" dialog has a "Saving from:" field containing a path like
"mailbox:///C|Windows ..."
For the .eml attachment it also has a "To:" field containing a path like
"C:\WINDOWS\fred.eml"
for an attachment named fred.eml
For a .txt attachment, there is no "To:" field.

In any case, when the mouse button is released, the "Error moving file" dialog
appears.

Hmm.  Do the workarounds at bug 253711 comment 2 and 4 help your situation?

Bug 252479, reported on Win98, WinNT4, and Win2K (but not, yet, on XP) concerns 
an error displayed when dropping an attachment onto an application icon, but not 
onto the desktop/Explorer window.

No. I should mention that holding CTRL changes the Error dialog to "Error
copying file" Cannot copy file: File system error (1026).

Just tried this - the behaviour doesn't change from trying to drop into an empty
explorer folder.

A couple of references:
One from MS which tries to blame disk space or the file system. I don't think
these are issues in my case.

This may also be enlightening. It may be the same problem this guy is seeing in
a different context.

OK, I dug out the Win98 laptop and tried this -- the error appears as described, 
TB 1.0 and 1.0+0222, Windows 98.  Also with Moz 1.8b-0120, Win98.  (Only tested 
on Win98 with Local Folders/POP mail.)

On dragging an attachment from a messager under Windows 2000, if I hold the 
mousebutton down while dragging, a transfer (or download) dialog appears --
  Opening From: mailbox://[etc]   (or  imap://[etc])
  Status:
  Time Left: Unknown
  Time Elapsed: 0:00

Under Windows 98, in Thunderbird, that dialog does not appear; but it does show 
up with the suite.

Can you try this with the latest nightly?  It is possible (but I think I am
reaching here becuase this does not match any of the symptoms in the other bugs)
that this was "fixed" by the checkin for bug 125386 which corrected several
other issues with Windows mouse event handling.

Sorry for the delay - I finally found time to try this with Nightly build
20050302. The 125386 bugfix doesn't affect this one. The behaviour hasn't
changed w.r.t this bug.

sorry for the spam.  making bugzilla reflect reality as I'm not working on these bugs.  filter on FOOBARCHEESE to remove these in bulk.

if this is a w98-only bug, and if it still affects trunk, it will not be fixed - win98 will not be supported for Thunderbird 3
