Sims 1 Legacy Collection Window Size Issue

Sims 1 Legacy Collection only launches at my base monitor resolution, and when put into windows mode with ALT+Enter, it makes the window a lot larger than my monitor, because of the title bar and frame, and it covers my task bar, which covers my other applications, which is why I prefer Windowed mode in the first place. 

I would prefer to select my resolution. Some people said a fix is to change resolutions and press ALT+ENTER to adjust it, then change back... but this messes up my desktop organization, and the sims gives me a warning that switching resolutions isn't supported and it closes, meaning i cant do nothing about it.

some people said ALT+ENTER would "cycle through options" but the only options I seem to have are "Max display resolution windowed" and "Max display resolution fullscreen" I have seen screenshots of people hitting it again and getting what looked like 1600x900, and that would be great if it worked. 

I would like to be able to have a smaller, floating window on my display that is not 100% as big as my display's maximum resolution.  Is there an Options.ini or some kind of steam launch instruction that would successfully make this happen?
