Bug: Calculate subfolders size automatically & column sort

[champ]

When that "Advanced" option is active and I sort the size column, the folders are only sorted by size once. If I leave the folder, or enter another folder, only the file's are sorted by size, while the folders return to alphabetical sorting. Perhaps this is the intended functionality?

I'm using 1.2.0.0 LITE on winXP SP2.

since folder sizes are obtained in the background asynchronously, sorting by size must be manual, after all sizes are retrieved
