Build Identifier:
function executeFile() (presented in the html code below) works well with
Firefox 2.
With Firefox 3, .bat files are executed but :
- DOS Window doesn't appear
- Firefox waits for DOS response
DOS response is never given.
Firefox is blocked.
If I try to open calc.exe instead of cmd.exe, the window appears.
How can i do to work with DOS under Firefox 3 ?
Thank you in advance for your help.

Summary: run a dos process → process.run with a .bat file doesn't show DOS window and blocks
I can reproduce this bug.
It appears that only the first DOS window is hidden. So, using a "bat launcher script", it is possible to bypass this bug until the fix is released.
Here is an exemple of such a "launcher" :
launch.bat :
start /WAIT %1
And change the executeFile() function like this :
file.initWithPath("C:\\launch.exe"); //(assuming that launch.exe is at c:\...)
[...]
args[0]="C:\\instance.bat" //(assuming that instance.bat is the script you aim to execute)
The result is that the first shell (the "launcher") is hidden, but the 'start' instruction in it forces the second window to appears.

Bug still exists but in a different way (tested under FF 3.6.10):
- DOS window appears (good point)
- but, when scripts ends, Firefox isn't blocked anymore but it launches the script again... and again... and again... like a loop, but there's no loop in the JS code.
With calc.exe, there is no problem.
