- Have only the tree on the left and a folder view on the right
- Have two tabs opened with drives/folders being c:\ and d:\
- Active tab is c:\
- Close it by pressing Ctrl+W
Result:
The first tab gets closed, the second tab gets activated
Problem:
The tab´s label is "D:" but the contents shown below are those from "C:". With ProcessHacker I can see that FC also still has the file handle opened.
