Dear Customer,
Thanks all for posting.
Based on the description, this issue only happens occasionally. I
understand that you have installed Vista SP1. Let us monitor this issue for
a while. If this problem continues, let us perform the following
troubleshooting steps:
Suggestion:
===============
1. You may try Brink's solution to check if the issuer re-occurs.
Windows HotKeys
2. You may try to perform a clean boot in Windows Vista to disable all the
third party application, and see if the issue re-occurs. In this way, we
can isolate the influence of additional applications and services. As you
know, many third party applications or services may interrupt the proper
operation of Windows.
Please refer to:

3. If the problem still exists, it is recommended you replace the
problematic keyboard with a new one. In this way, we can isolate any
hardware issues.
If anything is unclear or you have any updates, please feel free to let me
know. I am glad to be of assistance.
Hope it helps. Thanks.
