Problem the Macros with Corel X3

I have almost all macros. São very interesting. However the macros Thumbnailer, SelectRuler and DeleteSegment they cause problem with Corel X3. Here after run the macros Corel doesn't accept the commands of leaving, close and any other command. The macro Thumbnailer doesn't appear on the available macros section to drag a button for the toolbar.

Because does this happen?

BTW.: I sent an e-mail suggesting the macro translation Calendar 4.1 to the Brazilian Portuguese language and anybody answered me. I think that could at least answer the e-mail.

Thank you very much!
