Bochs 2.6.8 from rapps.
Bochs has 2 main Windows: the "console"-window and the "Display"-window.
The "Display window" has a speciality that it may be covered by a modal messagebox when the emulator "Panics".
-and start a simulation without configuring anything
-The simulation will give a modal "Panic box" soon (that is modal to the "Display window")
-As soon as you click "Kill simulation" in the panic box, the "Display"-window should vanish immediately
-The "Display"-window does not vanish immediately but is deactivated and is in a "zombie"-state where it can not longer be activated by clicking to it.
-It will automatically close as soon as you right-click the "Display"-windows tile in taskbar though (without selecting anything). It's as if WIN32SS realizes then that the Window does not really exist anymore.
I am pretty sure it is related to the modality of the panic box somehow.
jimtabor noted before that this misbehavior maybe timing dependant, however I can make it happen reliably here on VBox4.3.40.
