INI file does not use defaults when upgrading
The other day I noticed that my "recent workspace" list was not shown at all. It looked like it did not work.
The default set for workspaces is 15 and that works when you create a new INI file.
The default however is NOT used when the INI file already exists and it justs add a new element.
So in my case the recent workspace list was setup as having 0 items.
