I'm back! After a good night's sleep, I thought I'd try again. (I've got to stop playing with my system at two in the morning... nothing good comes of it.)
I see you added an additional way to get the Vista sidebar into Windows 7. I used the new method and it worked! Mostly...
I have the Vista sidebar, with the multiple page function and the mini sidebar toolbar on the top... which is good. And if I click on the "+" to get more gadgets, it takes me to the gadget box. (Again, good so far...)
When I click on the "Get more gadgets online" link in the box, it takes me directly to the Vista gadget webpage. That means the sidebar itself is the Vista sidebar. Great!
However, I still have two problems.
1. If I try to grab a new gadget from the webpage, it never installs. Whether I tell it to "open with Windows sidebar", or I save it to my desktop and try to install it from there, the gadget never installs. Nothing visible happens at all. It doesn't appear in the sidebar, nor in the gadget dialog box. If I check Process Explorer, I can see the sidebar.exe running... so it may be trying (and failing) to open the new gadget. I dunno.
2. The gadgets that appear with the sidebar don't seem to be Vista gadgets. I think they are the Win 7 destop gadgets I installed a few days ago.
In short, I think I have the Vista sidebar, but its filled with Win 7 gadgets.
I also seem to have gadget files in three separate places... in the new sidebar (x64, renamed "Windows sidebar"), under the old sidebar (renamed "Windows sidebar (2)"), and in Windows sidebar (x86). And they are all the same... all Win 7 desktop gadgets.
Got any ideas what I did wrong? Any advice is appreciated!
