Today 24U s.r.o. has released a new "must to have" product, 24U SimpleDialog Plug-In 1.0 for Mac OS and Mac OS X.
Provided you use FileMaker Pro, 24U SimpleDialog Plug-In will let you display almost arbitrary dialog boxes which combine text fields, passwords, checkboxes, and radio buttons. All this is as easy as the standard Show Message and Status (CurrentMessageChoice)...
Adding custom dialogs to FileMaker Pro was never so simple!
24U SimpleDialog Plug-in is available for US$24. You can find more information at the 24U Web site.
