I'm not clear about your question. What changes do you want to make to the database and why do you want to make the screen (of the database itself?) smaller? Changes are made to the database without changing its size, so do you mean because your sprite graphic is much bigger than normal that you want to change the size there in some way?
You didn't describe your problem, but I assume (like the poster #3) that your screen resolution is too small.
Please post your desktop resolution so that we can check that possibility.
If that is the case, there aren't many things you could do, as the minimum resolution for the program is stated in the requirements and that resolution IS neccessary. There are a few options available, but it all depends on how big your screen really is and on your windows version (you might change your DPI setting to make everything smaller in newer windows versions).
