The circumstances for this are a bit weird, but here goes...
- This only happens with Drive C: in Explorer View (I think because it's typically the first Drive listed), and it only happens if there are a sufficient number of folders on Drive C: to cause the below steps to make the Folder Tree list scroll down enough so that Drive C: has scrolled up beyond view (This also depends on the vertical size of the DOpus 10 window).
- Highlight drive C: in the Folder Tree.
- Double-click on a folder near the bottom of the list in the right pane to open it.
- You should notice that the list of elements of the opened Drive C: in the Folder Tree have shifted, or scrolled down sufficiently to cause Drive C: to scroll up out of view.
- Use the Folder Tree scroll bar to go back to the top of the Folder Tree.
- Click on the Expand/Retract Tree arrow next to Drive C: in the Folder Tree to retract the expanded view of Drive C: contents.
- Note the weird/scrambled order of the Folder Tree contents.
- Hovering the mouse cursor over the affected Drive listing area may straighten out things, but the sure-fire way in my configuration is to simply click once on the Explorer layout tab.
I hope someone can duplicate this. Quite bizarre, I'd say.
