Drawing order problems Lt2009 edu

I attach a jpg image on layer one, then outline all the parts I need using plines on layer two. I then change plines to splines using pedit. Sometimes one at at time, sometimes multiple. After that, I solid hatch areas that I'm going to cut away with my scroll saw. My problem is that for some reason, occassionally the newly created splines change their drawing order when I enter the pedit-s command. I have to select them and change their drawing order to bring them back to the top. Why does this happen and what can I do to fix it. I'm sure it's probably a setting I'm not familiar with. I was using Acad LT 2000 and I just started using Acad LT 2009, so I'm a little rusty. Also, Mininmize and Maximize don't work in the top right area of Acad, just in the application bar.

In other words, if I want to mininimize Acad and open another program, I have to use the icon in the task bar of Windows. Is this and Acad issue or a Windows issue?

You could send the JPEG to the back. And you can also turn off the image frame if the JPEG so you cannot select it. (If LT lets you do this)
