No

Regression is in Tk HEAD as of Feb 13, 2011.
Regression also appeared between 8.5.8 and 8.5.9.
Code to reproduce : http://paste.tclers.tk/2356

It appears that
1. Cascaded torn-off menus will not show up anymore when selected with the ------ line;
2. Non cascaded torn-off menus will not show up if their "parent" toplevel is withdrawn.

Looks OK with Linux. XP issue.

    The commit of 3-Jan-2010 "tearoff menus should be transient and use the toolwindow style on Windows" sets the torn off menu toplevel to be transient to avoid adding application entries to the taskbar along with setting the window type to toolwindow. Menu's have an odd hidden window hierarchy which confuses [winfo toplevel] so that the assigned toplevel for the transient command ends up being an unmapped hidden menu. As the owner is unmapped, the transient is unmapped resulting in the bug seen here.
    To fix, we exclude parents that are toplevels but also have a Menu class so that we find the first 'real' toplevel to be transient for.
