Q: I have setup a couple of search prefix in Tweakui, but somehow in one pc, I don't get to use them. They are ignored and the entire line is used as input to msn search. How do I fix the problem?

A: This can happen if the URL Search hook provider is broken. Use the following steps to resolve the problem:

Download RepairDefaultPrefix.reg from Mike Burgess' site:
http://www.mvps.org/winhelp2002/RepairDefaultPrefix.reg

Save it to Desktop. Right-click the file and choose "Merge".

If the problem persists, type the following command in Start, Run:

regsvr32 /i shdocvw.dll

Press Enter.
