Lectora 2008 button issue

thanks for the replies. i have no problem with creating new buttons; sometimes it's easier just because of the way buttons behave. i found the button issue when i was testing 2008 and wanted to be sure the problem exists outside of my courses and be able to explain to my peers what to do to avoid the problem if necessary. i think i will simply inform them the problem could occur and to rebuild the 07 buttons from scratch if they have to change them for any reason. thanks for the replies. i have no problem with creating new buttons; sometimes it's easier just because of the way buttons behave. i found the button issue when i was testing 2008 and wanted to be sure the problem exists outside of my courses and be able to explain to my peers what to do to avoid the problem if necessary. i think i will simply inform them the problem could occur and to rebuild the 07 buttons from scratch if they have to change them for any reason.
