This dialog box will appear when opening a file saved in an older version of building systems in ABS 2005. Has any one found a way to work around this dialog box, either programaticly or by disabling it entirely? Although ScriptPro has provisions to work around it, any sort of vba script (or i asume lisp) that opens older files will stall. Or perhaps, is there some way to detect the appearence of this box and automaticly send a "yes"? I've tried disabling AEC warnings, setting filedia to 0, nothing seems to effect it. Any ideas? -Chris The exact dialog: "This drawing was last saved by an earlier version of this application. Saving the drawing will upgrade it to the current version. See the ReadMe for details .... This drawing likely needs to have it's object's relationships updated. This could be a lengthy process but is recommended to maintain complete functionality. See the readme for details on drawing versions and regenerating object relationships .... Regenerate this drawing now?"
