- Commit a great experiment for explorer. Our explorer will try to load a library called rshell.dll which will provide an alternative implementation of some functions that are built in in windows shell. These functions are CStartMenu_Constructor, SHCreateDesktop, SHDesktopMessageLoop, WinList_Init and ShellDDEInit. Providing our own implementation for these functions will allow us to make it run in all windows versions up to windows 8 and also test the implementation of our own components that will be placed temporarily in rshell.dll while they are developed and debugged in windows. svn path=/branches/shell-experiments/; revision=61971
