There is one problem with Project options and Folders.
If you clear those INCLUDE and LIB fields, those are copied from global ones and Macros INCLUDE and LIB macros stay empty
Those fields should stay as user wants as Default-button is there for filling those.
If we are talking of the common practice (please look in my previous message) - the "default" button must reset (possibly wrong changed) settings to its defaults (=down to the point as the IDE was installed) values to ensure its (whole ide) flawless work without any reinstallation. At the moments it is just printing the value of the system path variable into the list box - that is whole shit (by the all means).
