+ I get some strange errors when I run multiple Internet Explorer instances on the same machine
+ ---------------------------------------------------------------------------------------------
+
+ Selenium Grid does not officially support running multiple Internet
+ Explorer on a _single_ Windows machine. This is mostly because:
 
-You would need a parallel test runner for Selenium Grid.
+* People who know IE better than I do (Dan Fabulich) tell me that if
+you run 2 browsers as the same user in HTA mode they end up sharing a
+singleton instance in memory, which could cause problems.
 
-I might eventually end up working on such a parallel test runner for HTML 
-test suites, nevertheless my time is limited and this feature is quite low 
-in my priority list: in my experience HTML test suites are a nightmare 
-to maintain you are better off writing and refactoring real code by the time 
-your test suite grows big enough that it takes too long to run.
+* The `*iexplore mode` is changing the registry settings at each
+session start/end to have IE use a specific Remote Control as HTTP
+proxy. If you run multiple Remote Controls at the same time you can
+see the problems coming! ;-)
 
-This said, there might be hope as some guys seem to be working on it though: see 
-[this thread](http://clearspace.openqa.org/thread/11482)
+**Currently, the only robust solution for running multiple IE instances
+with Selenium Grid is to use virtualization.**
 
+ This said, I am not satisfied wit the current state of affairs and I
+ am currently working on better support for IE in Selenium Grid 1.2.
