From what I have read, you exactly face the same problem to me. Run my machine using Maya_Mate. First of all, I tried creating new panel on the top screen without deleting bottom panel but after several hours customization on that panel I take reverse steps and feel happy to use default panel on bottom. Since there are no problem yet and ended the hours session by shut-it down. Later, on next login on my computer, I realized that that my active application icons does not show up on the bottom panel either the application has been maximized or minimize.
I installed Docky panel as an option to encounter the problem. Through out Docky, I capable to view my active application's icons. It is like temporary solution but I need solid solution. I have post the prob on linux-mint google+ community but there, still no answered by the correct solution yet. I hope for any Linux-Mint member who encountered the same prob or expert person to considered and share for any solution.
