Errors at LAYOUT command.

We found this errors at LAYOUT command.1. Try this :Commad LAYOUT, option Delete, name LAYOUT1 (at the drawing is only this layout) and IntelliCAD collapse with message:"Do you want save changes to the drawing?" When you answered "Storno", Intellicad will halts, when you answered "Yes", Intellicad will end and after reopen this file, creating some new layout and sets this layout active, IntelliCAD will always fall down. From this moments is impossible use created layouts. 2. When I create in IntelliCAD layout with small characters f.e. "new layout", this string is converted to "NEW LAYOUT". When I want delete this layout I have to write name of this layout as "NEW LAYOUT", not "new layout" !!!Also when I open in Icad a drawing created in AutoCAD, all names of layouts are converted to uppercase !!!Where is the compatibility with AutoCAD?
