' RapidFRM.inc (include file for RapidFRM.bas v1.41 and above)
'
' 1. Moved the mouse Decl/Func etc out of mainline code to assist in debugging
'    using RapidDBG. (NO debugging is applied to "$INCLUDE..." files).
' 2. QCOLORDLG - Fix for QColorDialog (pre-RAPIDQ2.INC v1.4e). Using this code
'    in case other users have not upgraded RAPIDQ2.INC v1.4e or greater.
' 3. QTABCONTROL - Some extra functionality.
