Although this doesn't stop me from working I am finding it REALLY annoying. I am unable to hide the Getting Started pages on the vSphere Web Client. I have tried both by clicking the cross and by clicking Help > Hide All Getting Started Pages. I have tried in Chrome and IE. Nothing happens. Strangely if a different user logs into the web client from my browser it works fine for them. Just my account 
.
Using version 5.5.0 Build 1588022.
Any ideas?
