I have an MSIWind running 10.5.7. I have put PhotoShop3 on but the screen resolution does not show the full windows so I cannot reach some of the buttons to adjust things nor reach the bottom of the windows to resize them. I wanted to run an external monitor but on plugging in a LaCie CRT monitor I just get scrambled graphics. Why ? Is there a fix?

If I plug in a 2nd monitor will I be able to see the Photoshop windows full size
or still only 1024x600?

Can any one suggest answers to this problem?
Thanks
