I've imported last version of source code using a SVN Client, and I get a "missing modIconChanger2.bas" error when opening the project in VB6 IDE. This file truly doesn't exist, and I guess it's needed in form frmProjectProperties, method cmdApplyIcon_Click, where it calls for a function named "InsertIcons".
This line renders the IDE unable to compile the project, but if commented the project seems to compile fine.
