our explorer behaves different on Windows XP compared to ROS regarding taskswnd pane activation Win-Key + Win-Key

ros r74969. Thanks for adressing the first 2 so quickly, this one is much harder I guess:

Repro:
-Open 2 Windows e.g: cmd & rapps_new (which both behave well regarding activation)
-One of those 2 windows should be active in title bar and taskswnd pane
-now press L-Win-key -> startmenu opens, window gets inactive in title-bar and in pane -> perfect
-press L-Win-key again -> startmenu closes, same window gets active again in title-bar and in pane -> perfect

Ros explorer executed on ros seemingly behaves perfect.
When you execute MS explorer on WinXP it would behave exactly the same.
Where is the bug, you ask?

Well, when we execute our explorer without rshell on WinXP, it suddenly behaves like that:
-press L-Win-key -> startmenu opens, window gets inactive in title-bar and in pane -> perfect
-press L-Win-key again -> startmenu closes, no window gets active again neither in title-bar nor in pane

Imho this points towards two bugs: one deeper in ros and one within explorer (taskswnd?).

We should adress the bug in our explorer here first when executed on Windows and then double-check how the fixed state behaves on ros.
