This almost works for me, however, I get an error during make that says:

! ETdlg.h:14: default argument missing for parameter 3 of
`ETDialog::ETDialog(class vBaseWindow *, char * = "Erase Tapes", class
ETTextCanvasPane *)'

Note that my ETdlg.h contains:
        ETDialog(vBaseWindow* bw, char* title = "Erase Tapes", ETTextCanvasPane*
_ETcp);

Should I go into v/includex/vdialog.h and modify:

    class vDialog : public vBaseWindow, public vCmdParent
to

    class vDialog : public vBaseWindow, public vCmdParent, public
vTextCanvasPane???

Where is this default parameter specified?

Thanks,
Phil
