User-Agent:       Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.0; .NET CLR 1.1.4322; .NET CLR 2.0.50727)
Build Identifier: version 1.5.0.2 (20060308)

In version 1.0.6 and above, when I receive an email with a .vsd (visio) attachment, and double click the file, the open window appears, but the option "Open with" is greyed out. I can only chose the option "Save to disk". 

Reproducible: Always

Steps to Reproduce:
1. Using Tbird version 1.0.6 or above, double click a visio attachment
2 [review]. Attempt to open using Microsoft Visio
3.

Actual Results:  
Recieved the "opening window", but the option "open with" is greyed out, the drop down box is empty and disabled, and the only available choice is "Save to disk".

Expected Results:  
The option "Open with" should be available, and the drop down box offer the programs which can open .vsd files.

Original summary:
> "Open with" is disabled when opening a Visio attachment

This behavior is deliberate, if not useful; see bug 280847 comment 5.  Since Visio supports running macros, a Visio file is considered an "executable" that possibly could infect your system; therefore, the "open" action is suppressed.

The thing is, .DOC and .XLS files are also executables, but they are much more 
frequently encountered, and so exempted.  Which seems contrary to sense, but there you have it.

The list of prohibited extensions currently is at:
  http://lxr.mozilla.org/seamonkey/source/xpcom/io/nsLocalFileWin.cpp#2356
The table is named "executableExts".

I'm changing this bug to a request to remove .VSD from the table.  (There are three other Visio extensions in the list: .VSS  .VST  .VSW -- these aren't typically the ones that people mail around, and typically wouldn't need to be opened from the message.)  In the meantime, a workaround is described at
