Applet focus issue with button after minimizing an maximizing. The getMostRecentFocusOwnerForWindow in AppletPanel may be at fault. Please see the comments section for the test case and steps to reproduce the bug.
Tested with latest 6u10
IE pass with both old and new plugin
Firefox has issue with both old and new plugin. When the page is restored from minimized state, focus is not on any of the two buttons. This is known firefox focus traverse issue.
based on the test results, the issue is basically not reproducible in 6u10 and need no forward port.
Observations with bug fix for this bug in Oracle ER 5.0_13rev b06 release
Tested with | 5.0u13b05 | 5.0u13rev b06
IE 7 | Pass | Pass

The problem apparently occurs in appletviewer, so this is a general specific issue and not plugin specific.
