//\\//\\//\\//\\//\\//\\//\\//\\//\\//\\//\\
// v5.0.6.01 22-Feb-2019 Dialing all in Now!
// v5.0.6.01 02-Mar-2019 FixedWell with MPP
// Menu items calling back across, etc.
// v5.0.6.02 08-Mar-2019 Batch Stuff & Debug
// v5.0.6.03 14-Mar-2019 ReSetPages Call.
// v5.0.6.03 16-Mar-2019 Split to simplify.
//\\//\\//\\//\\//\\//\\//\\//\\//\\//\\//\\
// v5.0.6.04 25-Mar-2019 FixedWell & nearly
// done. This is really working great now &
// with SomePages2! Design ready: CurrentPage
// PrintDialog Option to go into Selection.
// Nearly all of that Logic will have to be
// in ME. Since that's where BOTH
// CurrentPage & Selection are or are going
// to have to come from. And at some point
// I will have to ReRoute or Mod or ReTest
// the 2nd Instance Code in PrintForm2.cs
// in PrintBlaster Deluxe. Or Call Print
// Functions directly:
// from Smesa to MCPL eventually maybe.
//\\//\\//\\//\\//\\//\\//\\//\\//\\//\\//\\
// v5.0.6.04 29-Mar-2019 Tested & Clean!
// v5.1.6.06 13-Apr Sel & CurPag detail.
