Problems selecting text in 9-99-3 on Windows XP + open dialog focus

If I hold down on Shift and use the up/down arrow keys I can't select 
lines of text. I can select text by clicking and dragging, but when I 
get to the bottom/top of the window it won't automatically scroll on to 
allow me to select more text in the same drag. Also Ctrl+shift+end/home 
won't select from the current position until the end/beginning of a 
document.

When I do ctrl-o-o to open a file the file name text box has text 
selected but doesn't have focus, so typing doesn't automatically go to it

Regards
