Lag after removing a column

[ownedbycats]

Previously, I had two reading status columns: #read (tristate boolean) and #percentread (integer).

I recently updated all the templates I could find (column icons, composite columns, and some action chains) to check for a 0 or 100 in the integer column instead of true/false in the bool. All seemed to be well so I deleted the boolean column. Now Calibre is lagging every time I update a column.

I put back the boolean column and the lag went away completely.

My best guess is that I missed a template somewhere and it's trying to update based on the nonexistent column, but I can't figure out where it might be -- I scoured all my composite columns, and as far as I understand column icon rules remove themselves when invalid.

For now, just to kill the lag I just created a composite that returns 'yes' for 100 and 'no' for 0.

Any other idea where I should check?

I ended up using SQLiteStudio to make a dump of my database so that I could use Notepad++ to search for the column name. (Except Notepad++ didn't like the size of it, so I ended up using EmEditor instead.)

I'd left a #read in a saved search used in one of my virtual libraries. And from there a composite column checking virtual_libraries(). Oh, and a column icon checking the virtual library column. That would probably do it. I changed it and the lag's gone.
