Download Gadget Manager (click 'save as' to save the program somewhere to run it from...no installation is necessary)
Here's a little helper app for the sidebar. The main purpose of this first version is for easily switching the sidebar between 32 bit and 64 bit modes. We may add more functionality to this app later if there is a need. We also threw in a link to "view a list of running gadgets" since this menu is not as easy to find in Win7 as in Vista.
You'll also notice there is an option to always run the sidebar in 32 bit mode. This is an experimental feature that will basically hijack the sidebar anytime it's started(like when Windows restarts) and make it run the 32 bit version instead. This can be very handy so you don't have to always manually reset the sidebar to 32 bit mode. Make sure however if you check this box, not to delete the Gadget Manager program since it's required to handle this feature.
If you ever get an error like "Windows cannot find ''. Make sure you typed the name correctly, and then try again." that means the sidebar is set to always run in 32 bit mode, but on startup, it couldn't find Gadget Manager to do this. This can happen if you move or delete the Gadget Manager.exe file. The solution is just to start up the Gadget Manager from wherever it is located(redownload the file if you've deleted it) and it should automatically reset the settings to handle the 32 bit sidebar again.
The program can also be run with command line arguments(useful if you want to create shortcuts). Here are the arguments:
/rac - Run a command and then close the gadget manager(without this the manager window stays open)
/go64 - Switch sidebar to 64 bit mode
/go32 - Switch sidebar to 32 bit mode
So "Gadget Manager.exe /rac /go32" will switch the sidebar into 32 bit mode.
