VS wont step into debug

Visual Studio 2003 C# .net
It's a recurring problem, Ive several breaks in my code and the debugger
doesn't stop when it hits them. Sometimes it will, other times it won't.
If I start by pressing F11 it will step into the program ok but after I
press F5 then my breaks are ignored as usual.
Is there anything I should be looking for (aside from "debug" being in the
build window?)
thanks
Claire

Try a 'Rebuild Solution' (if that is possible with C#).

Probably some object files have not been updated so their debug info is
inconsistent with their source files. Common problem under VC++.
