I have a new laptop, the old one died. Now I notice that when I open a window of a web site such as TSG, the window is minimized to about 1/4 of the screen.I have tried the following, and none seem to make the maximized window "stick"1. I re-sized the window and closed itdidn't stick.2. I re-sized the window and closed it holding down CTRL didn't stick3. I re-sized the window and closed it using the file option + exit didn't stick.
