Well if that is the case then I will either use the program (Database Oasis) as is - most is still at least readable - or worst case it gets dumped. I'm not even going to try changing the text size to test it. Last time I did when I changed it back a lot of text items were changed and I had a heck of a time getting them all back to what I need. Very similar to when I used XP Pro; I tried changing my resolution to 800 x 600 to accommodate one lousy program which would not render decently at all and the developer insisted that the majority of his users were still using 800 x 600 resolution and that I could just change it for his program and change it back afterward. Of course when I tried that my desktop was a complete mess - icon sizes did not change back automatically - as well as other areas throughout the system. I committed myself to two personal rules then: One, I would not change my resolution willy-nilly to accommodate one app out of the many I use, and two, that I do not need to use the products of any developer who through laziness or lack of programming talent did not update his/her program's UI to keep up with current screen resolutions, monitor sizes, etc. So I will contact the Database Oasis developer to report what I am experiencing here and see just what kind they are - the kind I'll keep or not.
BTW, I recently had a similar experience with another "one program" developer - actually not a developer at all but a person who wanted to develop a specialized database program. He contracted with a software "engineer" to create this program that he had conceived. The initial pricing was outrageously high but later dropped quite a bit - wonder why?!?

After installing the program it initially opened its main window. Tiny. After trying and failing to resize the window I measured it: 740 x 570 px. Works out to less than 20% of my total screen size. The text all looked decent - for a little window like that. Proportional is a better way to put it, I guess. I wrote to him but he told me the window size could not be changed and that I should just change my resolution to 800 x 600 and it would look much better. Turns out that wasn’t the only thing I didn't like about his program. Can't scroll with the mouse wheel, can't tab from/to text input boxes, can't use any of the Microsoft shortcuts for text formatting like Ctrl+B, Ctrl+U, etc., or for copy/paste, like Ctrl+C and Ctrl+V. This app looks like it was designed to use in DOS Shell on a 10" - 12" monitor. I only got it because it would have done a needed job for me if it had worked, and the price had dropped to the teens so I didn't lose much $. There was no trial for it - I believe because the guy had no idea how to make it work only for a time and then stop. His "software engineer" just signed him up with an online activation outfit; activate once and done.
Oh well, I'll learn one of these days.
Thank you.
