My panes are disappearing off to the right of my screen and I cannot see to do any work

I use CMS for content and I am trying to make changes to pages - but my right hand pane has disappeared off of the screen and I cannot get into the pages I need to to make changes - this started happening last week and I cannot work at all at the moment. Is there a screen configuration page?

There is no screen configuration page, AFAIK.

I am trying to understand the problem better. What do you mean that you cannot get into the pages?

Also, do you by chance have this environment deployed somewhere, so we can take a look at what’s happening?
