* Add more missing code. The custom CMenuDeskBand is now able to show the contents of a CMenuSite/CMenuBand in the right size, including the banner (not yet fully functional). * Organize the method list in CMenuSite by interface. [EXPLORER-NEW] * Revert the hacks from r62134. [PSDK] * Add IUnknown_QueryServiceExec to shlwapi_undoc.h svn path=/branches/shell-experiments/; revision=62149
