Hi,
Well, it looks like I have to supply my own answer

The Tasklist that is referred to goes back to Oct 26 2008,
so nothing has been done about it for well over a year

I accomplished what I wanted by using either one of 2 utilities:
Utilities to set Bowser as Default:
1.DefaultBrowser
http://windowsxp.mvps.org/defaultbrowser.htm2.SetBrowser
http://www.pc-tools.net/win32/setbrowser/Actually, I used the 2nd one first and it works ok and opens links in email and documents in QtWeb.
Tried this on XP (SP2 or SP3) ,but not sure if it'll work on Win7.
Use at your own risk

Pete.
