Description Kim Horne

2005-12-02 10:53:36 EST

Upon updating to the latest I build I got a "Workbench Layout Reset" dialog.  In my log were the following stacks:

The problem is that updating on the Mac blows away your config directory.  Before upgrading I had installed the PHP editing plugins and when I shut down I had one of their editors open.  The failure to find this editor on startup blew away my layout.

Is this still a problem in 3.3?

I think this was a transient state

This just happened to me in I20080207-1530. As mentioned in comment 0, I also left an editor from a third-party plug-in open, and then restarted the workspace without the editor's contributing plug-in available.

Whenever I try to open the editor tab overflow menu (called "Show List"), I get the exceptions below and the affected editor's icon is a big red square.

Eric, this is also affecting RPT - how timely that you should see this again Markus!

We've implemented new and exciting ways to make perspective layouts disappear (model driven renderers).
