Hi Hahn,
Thank you for your prompt reply. Unfortunately I have tried blowing air and brushing the area gently without success. And even more unfortunately I believe it is just out of warranty though will double check - only just over 2 years old which seems a very short lifespan for such an expensive keyboard.
Disappointingly this is the 3rd sculpt keyboard that has failed in the same way for me. It's such a shame because I really love the keyboard, it's the most comfortable I have ever used. Looks like I will have to give up on this model and look for another that is more sturdy
Thanks again for the advice
Regards
Angela
