If you have set LiteShell as your shell, Explorer will load its shell when you open a folder. To stop this behaviour, open the LiteShell Control Panel to the "System" tab and select the "Disable Explorer Shell" option (this is not available when editing the global settings).
Also, if you like to use multiple explorer windows open at once, open an explorer window and select 'Tools | Folder Options' from the menu. Choose the 'View' tab and check the setting labelled "Launch folder windows in a separate process".

Under WinXP, the WIN key refuses to work unless explorer is running. I do not know why this happens or how to fix it. Sorry :(
This is best illustrated by an example. Say that you want a menu item called "Videos" that creates a sub-menu which lists the contents of the folder "C:\My Videos". To do this, you would create a file called "Videos!PopupFolder" in your LiteShell menu directory. You would then open this file in notepad, type "C:\My Videos" (without the quotes) and save the file.
Bosskey 2.00 allows you to switch between multiple (virtual) desktops. It can be used with LiteShell, but some extra configuration is required. Open Bosskey's configuration window, and type "LiteShell" into the text-box in the section labeled "Always displays windows...". This will ensure that LiteShell's desktop window is displayed on all virtual desktops.
TrayModule is a third-party system tray written by Anish Mistry. To the best of my knowledge, it is the best available system tray.
This is a bug in the Windows API. It annoys me, but I cannot find a fix.
