Focus Bouncer

Installation: Download Focus_Bouncer.class to the plugins folder and restart ImageJ.
Description: This plugin illustrates a problem that can occur in ImageJ 1.20i and earlier when rapidly opening a series of windows. ImageJ could get in a state where the focus was rapidy bouncing between two or more windows in an endless cycle until the user clicked on close boxes a few times. The problem was most likely to occur with Sun's Java 2 JVM (JDK 1.2 and JDK 1.3) when using shift-R (Process/Repeat command) to rapidy run multiple copies of this plugin. This problem is more likely to occur in versions of ImageJ prior to 1.14.
