Hello All, I'm trying to upgrade to 10.3. When my machine reboots to begin the initial upgrade questions, I select the language and click 'continue'. I'm now presented with a screen that basically says 'To continue with installation process, press continue.' I try to click on the 'continue' button but nothing happens. Its not that I can click the button and the machine just sits there. It appears that the window and the button are inactive and just a graphic. I'm also unable to select from the menu at the top of the screen. My only ability is that I can still move the window around the screen. I have 2.3Gb of available space. I see that the basic upgrade requirement is 2Gb but is this cutting things too closely? Do I just need to wait longer for it to do a full scan? If any of you have experienced the same problem, how did you guys get around this? Thanks in advance.
