I cannot find any options to help my problem. For some reason, whenever I double click the desktop, opening DOpus, the DVD-R opens up. This is irritating, and I haven't a clue why it began or how to stop it. I close Dopus while there is only one TAB open, opened on the hard drive. Yet it always causes (regardless of reboot or not) the DVD to open up. DOpus is running on Vista SP1 x32. Any help would be greatly appreciated. Thanks.
Does the same thing happen when you open Opus via other methods, e.g. right-click the Desktop and choose New Lister? If not, have you altered what the desktop double-click action performs?
Does it only happen if the Tree is visible in Opus?
Does it happen with Explorer as well? (Try with the tree visible there as well.)
Another thing to try is closing any toolbar in Opus which displays a list of drive buttons.
I'm not sure if any of those things will be behind it but they are the only things I can think of which enumerate the list of devices and thus may involve the DVD drive when the HDD is being shown.
