I was comparing FF2/FB1.05 with FF3/FB1.2.1 and also FF2/FB1.2.1. And for the record,
1.3 is much faster! It steps as fast as 1.05 did, and most notably it loads the file MUCH faster. Thanks =) I notice that in 1.3 the file is scrolled as I step to keep the current line in the middle of the window. Is there a setting to change this behavior? It's hard to follow because I get a lot of flicker as the file moves. Thanks, Chris PS - Sorry if this is a double-post, I thought I replied but it wasn't showing up in the thread so I'm resubmitting.
