Uninstalling and running CCleaner seems to have fixed everything. The latter was the crucial step.
Grrrrr! I had a lot of trouble with OD+ when I moved to Win 7. I finally got everything working except that it continually grabbed 25% of one CPU. I played with a combination of Tiles and Fences for a while but decided to give OD another chance.
Many of the problems I had when I first moved to Win 7 are back:
OD refuses to load at boot time even though it's listed in the Startup programs and msconfig. No error message at all, just doesn't load.
Drag and drop doesn't work. If I drag an icon to the dock I get a circle with a slash and I can't add it.
Dead Chrome icon: The properties are identical to the standard Chrome icon properties and yet it opens a Chrome window that does nothing. It won't even try to load any webpage, including Chrome's internal pages such as settings, history, etc. pages. Even though the icon is dead it does show the Chrome page thumbnail when I hover over it and will restore it on a click. That tells me it's hooked properly but just refuses to act as a browser.
Of course I've tried an uninstall/reinstall without success.
Help!
