Since the recent update of Windows 10 I have noticed strange behaviour in Opus 10.
The first is that there is a delay between clicking on a drive or directory and the content being shown in a display panel, and the second is that the footer bar is now black
You can fix the status bar by either turning off the glass status bar option or upgrading to Opus 11.
(Windows 10 made breaking changes to the way glass is rendered which required changes on our side. Opus 10 was made many years before Windows 10 existed and is no longer being updated.)
The delay could ve many things. Does it only happen once for each drive? In Explorer as well as Opus? (Or in either but only if the drive hasn't been accessed recently?)
