Thanks for the help Leo.
I checked those settings and everything was off. I even checked the installer and well that too did not have any compatibility settings on. After uninstalling, downloading the installer to a separate location and almost deciding to restore to a backup I decided to undo some visual tweaks for windows that I had in place in the registry and sure enough that fixed.
I discovered that changing the windows title bar size and its font size effects the details view in File Explorer and the windows tree view icons. I never cared to notice this since I never use explorer, but now Directory Opus 13 is also effected by this registry setting
Below is a small utility called WinAero. It lets you change the title bar size and its font size, its on the left side of the screenshot.
First screenshot, the title bar size and its font size is set to the smallest size possible. File Explorer/Opus windows and their tree panel icons are effected:
Second screenshot, the title bar size and its font size is set back to the default size. File Explorer/Opus windows and their tree panel icons now use their normal sizes:
This is very bad.... on so many levels. This defeats 'the self contained settings' feature of Opus. Many of us who use Opus as a portable application. We cant be expected to change registry settings of the current computer
I use Opus on my Surface Pro a lot. This windows feature to reduce windows title bar sizes was the best remedy I could come up with to save screen real estate. Using Opus on the Surface Pro now is just unbearable.
Please don't become like Explorer forcing things, Opus 12 was doing things perfectly fine with its own self contained settings.
I will have to go back to Opus 12 now. I don't have a choice, I am not rescinding my license, as I still want to use Opus 13. I hope you fix this issue, until then its Opus 12 for me.
One quick way to fix this would be to allow us to hide/turn of title bars, you were asked many times to do this and I was disappointed to see that it was not mentioned in Opus 13.
Well here I am you kindly requested this feature; please let us turn of or hide the title bars, even if just for Listers. It does not need to be a default setting but should be available. That would be ideal for me and many others. This is an important feature for people with small screens.
