Resizing Oversized Window

I installed openSUSE on my macbook pro 7,1. As of now I am trying to update the software, unfortunately, I have encountered a problem. As I hit the “Install Updates” icon, I get a window that gives me a readout of the current updates. No problem there. However, after I click the “Update” button, a second window pops up that gives a very long list of other software that needs to be either removed, installed, or updated for the original updates to be installed. Only problem is the list is so long, it extends beyond the visible desktop. This is a problem because I cannot click on the button to install those updates. The window cannot be re-sized, so there is no way I can reach the button, and I have even tried rotating the desktop 90 degrees (to make it longer), but still to no avail, as the install button is out of reach even then. I don’t know how I can update the software if I can’t hit the right button. Is there perhaps another way to get around this (like with terminal)?

Hold the ALT key while pressing the mouse button to move the focused window. Move it up/down as needed.
