I've found a problem with the "Save As" function. If you do a save as over a file that is open, the file cannot be activated from the toolbar

When I write a macro to select text to delete, it doesn't. I do a startselect, FindParam (to find where I want the block to end), EndSelect, DeleteBlock. The select just doesn't seem to occur. Why not, and how do I?
Macro:
Param1 "Directory of"
FindParam
LineStart
CursorDown
StartSelect
Param1 "File(s)"
FindParam
LineStart
EndSelect
DeleteBlock
