Error remember the visibility status of custom column

I have found a bug regarding the visibility of non-standard columns.

On a couple of occasions the program ignores the fact I have hidden a bunch of custom fields and starts to show them again.

I notice that it seems to remember my settings for standard ones, but treats custom ones as new ones that it has not seen before and I guess the default behaviour is to show them.

It seems to be caused by the fact I was not on a network when I loaded the program at first. After it gave me a message about the SOAP API not being enabled (which is kind of ambiguous in this instance) I then quit, switched to wireless and then re-ran it.

At that point it connected fine but now showed all the columns I had previously hidden.

To confirm the problem, I unticked some of them, quit, reloaded and those columns were still hidden.
I then quit again, disconnected from the network and reloaded. I got the message about the SOAP API and noticed that only the standard columns showed (I guess these are hard-coded in the program).
I then quit again, reconnected to the network and reloaded.
At this point it connected fine and reverted to showing me all the custom columns including the ones ticked just before, while still remembering the standard ones that I always have hidden.
