Is the Online Center in Quicken?
Yes, it's in the Tools menu.
Thanks @Tom Young I learned something new today. I rarely go to the Online Center, so I was not familiar with that feature.
Not possible. You can make the area larger by grabbing the border and strecthing it upward. To find the border, slowly move your mouse up until it turns into the double arrow. It is higher than you might expect.
There's a couple of things you might do here. One is to increase the size of the Downloaded Transactions window. Grab the line just above the title "Downloaded Transactions" and expand that window. The other is to go over to the Online Center for that Account and you should see the transactions there as it's a larger window. You also can print the downloaded transactions from there.
