Why does clicking the refresh button collapse the folder tree?

[ncnnnn]

before refresh:
 
 root
      a
        ----b  This is the current directory
      c
        ----d

after  refresh:

 root
     a
       ----b
     c

That because when you refresh it actually rebuild the entire UI tree and make sure that all folder and files are in sync (exists)

ok. thank you.

Recently, I have been using mapped Linux. I modified files under Windows, but it's difficult to automatically sort them to the top based on modification time. Clicking the modification time repeatedly doesn't update it. I have no choice but to use the refresh button. However, the refresh button not only refreshes the file panel, it also collapses the folder tree during synchronization.

The tree is not refresh if you just refresh the filelist   the refresh button above the tree is for the tree view.. if you press the refresh above the filelist. the tree is not refreshed. of if you press F2/F5 (depending on setup) to refresh when focus is in the file list only the filelist is refreshed

Yes. I clicked the refresh button on the file list. The problem might be caused by focus. If you click the refresh button on the file list after clicking the folder tree, it will collapse the folder tree. Sometimes I also try to refresh the file list by switching folders and then switching back.

press the other refrsh button in stead.. dont press the refresh for refresh folder tree if you do not want to refresh that.. then press the refresh for the file list
