In front of each folder, I used to see a box with a plus or minus sign inside indicating whether there where additional subfolders or not. I updated my OS from XP to Win7 and now using the same Dopus configuration, I don't see these boxes any more. Instead I see some arrows that appear in front of the folders that contain subfolders, although only when I hover the mouse over that lister. Looks like explorer does this, so it must be a new Windows 7 feature (which I hate BTW). How do I get the good old pluse and minus boxes back!
Thanks

Open the Preferences window then type tree into the filter at the bottom. That should make it easy to find the tree style setting, which is what you want.
Even with your suggestion I almost gave up, but then I tried the "Lines" checkbox. I'm not sure what Lines has to do with the plus or minus symbols but at any rate, that worked. So, back to being a happy camper 
Thanks

Because there are three tree styles. Vista, which has no -/+ boxes, -/+ with lines and -/+ without lines...
