Running WinXP here and F&R 1.05.12. When I run Opera 8.0 normally, I don't get prompted to set it as the default browser. When I run the Opera desktop shortcut via F&R, I do get prompted. I figured out the reason: F&R launches applications using SFN, rather than LFN.
I can duplicate the issue from an ordinary command line: If I run c:\progra~1\opera\opera.exe, Opera gets confused.
No doubt Opera shouldn't be confused by this, but is there some reason F&R uses SFN, or any way around it?
