    debugger problems: line by line does strange things

    Hi all,

    i have a problem that i never experienced with VC6 or VC .NET 2002.
    i try to debug a dll by using a 3party app to load and use the dll, and then
    placing breakpoints in the code so that i can do step by step execution.

    this has always worked fine for me, but when i step into a function,
    suddenly breakpoints are positioned on empty lines that nonetheless seem to
    be executed when i press F10. if i try to position them again on the lines
    that they used to be, they immediatly disappear.
    i have the impression that the debugger uses wrong line numers or something
    like that.

    i am also under the impression that some expections do not seem to be
    handled anymore, since handlers are not executed even though i know that an
    exception is thrown (the 3d party app crashes due to unhandled exception.)

    i encountered this problem first with C#, but i figured it had something to
    do with the .NET framework. now it seems that it also happens with unmanaged
    dll.

    does anybody know what is going on?

    kind regards,
    Bruno.
