Can someone remind me, where in the menu you can change the font size when converting? I cant seem to find it anywhere.

When you convert the LIT, go to Look & Feel and then base fomt size is what you change. Also I think changing Word Spacing is a good idea for more per line.

there used to be a way to change under delta, does anyone know abou this?

The font delta option has been replaced by the base font size option.

After reading this thread, I have downloaded and installed the 0.4.27 version and find that it runs incredibly slower on my machine than did the previous version I had installed. I realize that it does a lot more, but it takes a longer time from when I click on the Convert ebooks icon to when the dialog actually opens up, and then takes a while from screen to screen.

Is this standard or could it be local to my machine?

Another question -- I didn't uninstall the SonyConnect usb driver because I still want to be able to use that software to upload books to my reader. Might this be causing the slowdown?

I don't have the SonyConnect usb driver installed and didn't find the new version slower than before... (but I haven't tried version earlier than 0.4.18)

So far as I know there shouldn't be any slowdown. I certainly don't experience one, with or without the connect driver installed.
