This change makes heavyweight views listen to window events from higher
in the window hierarchy. If a move or resize event from higher in the
hierarchy is encountered, blocking modal components will be dismissed.

This patch should resolve an issue where the popupmenu for a combobox
could become 'stranded' if the plugin window was moved while the box was
open.

In very optimised builds, SHCore.dll may not be automatically loaded
into the address space of the calling executable. In these cases, the
call to `GetModuleHandle` will fail. Adding the call to LoadLibrary
ensures that the dll is loaded into the program's address space, which
will allow the call to GetModuleHandle to succeed.
