Troubleshooting
Problem
The Remote Control functionality of the Advanced Management Module (AMM) allows users to remotely control the keyboard, video, and mouse for a blade. Clicking inside the video screen for the blade will capture the client mouse. While the mouse is captured, users can send keystrokes and control the blade's mouse. When using the Sun Java 1.5.0_08 through 1.5.0_14, runtime environments and running Remote Control in Internet Explorer 6, pressing the Tab key on the remote client while the mouse is captured,will cause the mouse to exit capture mode. The Tab key will not be sent to the blade. The only key that is supposed to exit the capture mode is the left Alt. This issue is caused by Sun Java bug 6463919. To workaround this issue and send Tab to the blade, click the Tab key in the Remote Control applet toolbar.

Affected configurations
This tip is not hardware specific.
This tip is not option specific.
The system is configured with at least one of the following:
- Microsoft Windows XP 32-bit Professional, any service pack
Note: This does not imply that the network operating system will work under all combinations of hardware and software.

The Internet Explorer 6, Sun Java 1.5.0_08 - 1.5.0_14 utility is affected.
Solution

Workaround
Follow the below instructions to send the Tab key to the blade:
- Click the "Tab" button on the toolbar at the top of the Remote Control applet which is located between the Alt and F1 buttons.
- Continue using Remote Control.
Additional information
The mouse is exiting capture mode when pressing the Tab key in Sun Java 1.5.0_08 - 1.5.0_14 because Tab is one of the keys used to traverse focus from one component to another. In Internet Explorer 6, and running specific versions of the Sun JRE, applications are not able to turn this focus traversal off. When the applet loses focus, it releases the mouse and no keystrokes are sent to the blade until the applet regains focus and the mouse is captured again.
The workaround does not have this issue, because the user is not initiating a focus traversal by pressing one of the default keys used to change focus. Instead, the user is pressing a button in the applet that sends the Tab keystroke directly to the blade when it is pressed.
