This is something that is driving me crazy.
For some reason, I cannot close any "Getting Started" tab in the web client, neither by clicking the X at the individual tab level, nor the "Hide All Getting Started Pages" link under the help menu. The links act as if they are working, meaning that I get no error, but the Getting Started tabs persist. Interestingly, once I click on the link under the help menu, the text changes to "Show All Getting Started Pages" as if it was already set. But regardless, those #%$*! getting started tabs remain.
Anyone else have this issue and have a fix?
