I have Preferences -> Listers -> Options -> Ignore folder format of Default Lister checked.
Folder content type detection is not enabled.
I have no folder specific formats.
Collection, Flat View, FTP, and Synchronize formats are checked, but shouldn't be relevant.
Based on the above, I think the only relevant format is Custom.
In the Custom format, the width of the Size(bytes) column is 111.
My default lister consists of several tabs.
If I open the default lister, all the tabs (except the irrelevant My Computer) have 111 for the width of the Size(bytes) column.
I open an additional tab, set the width of Size(bytes) in that tab to 200 and Set Default Lister.
The next time I open the default lister, the width of Size(bytes) in the tab last added to the default lister is 200.
What am I not understanding here? I thought Ignore folder format of Default Lister would cause the entire format of the default lister to come from Folder Formats, in this case the Custom format with a width of 111 for Size(bytes).
The above is, of course, a silly exercise except that it is a relatively easy to explain example of a more general misunderstanding.
