Yes. You probably already know that you can resize the main window as you can with most other apps in Windows, by clicking the minimize and maximize buttons in the upper right, or by grabbing the lower-left corner and dragging it until the window is your desired size.

However, I assume you're asking about the dialog boxes (aka "popup windows") such as the Lineup, Defense, Bullpen, Sortable Stats, etc. To change the size of dialog boxes, go to Options on the Tools Menu and change the setting for "Dialog Box Size":

This is the Sortable Stats Dialog in Football Mogul 17:

I use this dialog more than any other feature – for analyzing my roster, signing free agents, or digging deep into the college draft pool. I can pick from 108 different stats and ratings and sort by any of them. And I can right-click to copy it all to the clipboard and drop it right into Excel.

Now you select an entire group of stats with one button click, and that click also automatically updates all the stats being displayed and resizes all the columns to fit evenly across the screen.

Baseball Mogul and Football Mogul aren't just games – they are pieces of software that we spend many hours using. That's why we're constantly reading your emails, eating our own dog food, and making improvements to every aspect of the game. A realistic sim isn't much fun if the software doesn't let you do the things you want to do with it.
