Explorer error fix..
Problem example:
Right click My Computer, select Explore.
Click on search on the toolbar, then on "Other Search Options".
Click on "search the internet".
Place cursor at top of pane - you may see the 912945 'click to activate or use this control' hover.
Click on customise. Page is stuck on "loading search settings" and any attempt to select a radio button the window throws script errors.
Fix: Run the following command:
regsvr32 /i shdocvw.dll
The first time you try to use the "explore" context menu there may be an extended delay, with the system frozen, before the window opens. Give it a minute or two.
Thanks to Rob A who mentioned he'd been able to fix a problem with his "Search the Internet" feature by registering that file - don't know what his precise problem was, but what the hey, it works :o)
