Does it matter if I run preverified class files through DashO™ Pro?
It is OK to run preverified classes through DashO™ Pro, but it will strip the extra information added by the preverifier from all classes that it outputs. This means that you must preverify your output classes after running DashO™ Pro on them. The reason for this requirement is that DashO™ may invalidate the information inserted by the preverifier when it transforms your class files.
