What is good this early in tha morning???Post blueberry cerial with some real blueberrys from superwalmart.... One very important topic of this software was the "LAYOUT" that means the way the software looks all alone on the screen"idle"??Do ya understand what all of the buttons do???No no don't push that one."Wait until I finish". All of these buttons have alphabetic & numeric writing on them that will equal its subject "A button on your computer is labled Enter.If you press that button you will be performing the Enter function.So what is the subject of the button on your computer"metaphore" Enter = To execute a command /or function that will be performed on your computer.That equals the value of Enter.But,who doesn't have something like that??? I enjoyed this software because it was microsoft tested and certified,and It was very easy to install and UN-Install whith out leaving crazzy files behind?and messing up your "baby","your home away from home","your mini condo" "your computer".. So I can now say that I wont be calling D&B and sending the software company..ect a bill for loading & Running Broken software that I found fer free..I am talking my own ears off???Well anyway Perturbation is two parts of this rendering beast that you can type in manualy/yourself.These two fields/Entry Boxes are outlined in a nice charcole black squibbly.The subjects in the outline is Real & Imaginary.Hmm go figure??This could be similar to a child bringing you a mushed cookie that has been in there hand through thick and thin at the end of a party,Saying Just for you....Well I am going ta have some coffee.I imagine that I will now be wearing the frctal forum over my broken head.There will halfta be some sort of simple notebook err something for this stuff because the user interface doesn't look like it will change in my lifetime....unless you buy software programs with big thick manuals.Ha.Ha but where would ya end backup???Forums
