Program opening in a tiny window that is maximized(all options greyed)

Hi All,
Coming back to windows from a long Mac exile and trying to set things up on my new computer, I am having an issue with one specific program: Wacom Tablet preferences
I downloaded the appropriate driver from the wacom website (it works, this is not a questions about wacom products)
In order to set up the device I need to launch their Wacom Preferences utility.
It launches fine, but in a tiny (perhaps 2 inches square?) window.
The window is too small to be used.
The window says it is maximized. The size and restore options are greyed out.

I have tried changing my screen resolution just to used this utility, but even at 800x600 its still the same (just relative to the different aspect ratio).
I also tried opening the file using the graphics card and the on board intel graphics - to no effect.
According to wacom this is the proper driver for my device and they claim it works with windows 10.

I would appreciate any help you can give me, thank you so much in advance,

Peter

I am running Windows 10 Pro, on a 15.6 ' Dell M3800

Hi Ken,

Thank you for taking the time to reply, I really appreciate it - unfortunately none of the previous version compatibility modes worked, neither did launching the program in different resolutions. Still in the banging head against wall stage here lol
