Comment 54 for bug 93546

hi malcolm

internet explorer has two possibilities to get multiple processes:
1. click on the normal start icon starts a new process,
   doing "new window" in an existing window uses the same process
2. enable the option "every window in a new process"
   then even open in a new window ends up with a new process
   probably the way you described it.

i never succeeded in clicking on the normal start icon without creating a new
process.

but in general i find this behaviour elegant ... somehow it seems to me that
other applications might have some code in it to look if there is already a
running instance of that application and and tell that instance to create a new
window with the new contents. it seems internet explorer is just not doing that,
so i believe strongly it is programmed like that and you cannot switch it off.

this means:
- you can log in multiple times (with one instance)
- one instance of internet explorer instances crashes
  with all its windows, no other instances affected

firefox by contrary looks for an existing running instance.
