Currently, the windows that pop up in the console, upon clicking on action buttons, along with the views for undocked components, are implemented as JFrames. This causes the following drawbacks:

• each window is seen as a separate application inthe task bar. This can be confusing and also takes a lot of taskbar space
• this can lead to inconvenient behavior when another application comes on top, then to view the JPPF windows again, you have to restore each one separately

To improve the current behavior, we propose to make all popup windows and separate views non-modal instances of JDialog instead of JFrame
