Hidden folders cannot be selected when comparing two folders (Windows 10). In the controls where the user selects the two folders, hidden folders are not shown so they can't be compared. For example, I can't select "C:\Users\<username>\AppData\Roaming\FolderA" because AppData is hidden. I tried running QuickHash as administrator but it made no difference.

The same type of tree view controls are used on the Copy tab, and hidden folders are displayed there. Would be helpful if the controls on Compare Two Folders behaved the same way.
