Editor performance on Mac OS X

Hello. I'm testing the software's performance on my Macbook 2.4 Ghz loaded with Mac OS X Leopard, and compiled with REALbasic 2008r4.
The performance of the editing seems too slow for real-world use. It is the basic slowness of time-to-update after I press a key. I feel like I can type as fast as I want, but the the updating is slow, and actually makes it difficult to type.
It would be nice to have greater performance so the editing was more comfortable.
I'm not sure how the internals are setup, but if you have your blinking cursor timer going, you should timer.reset it on each key press, and you should force the cursor/carrot to be visible on each key press. That would be a more standard approach.
Also, you appear to be updating far too much screen on each key stroke. I could understand if the current line, and possibly the lines below the current line needed to be refreshed (in the case of a word being pushed over the edge,) but the whole control doesn't need to be updated. And, just to make the cursor blink, it seems the only required update is the line at most, and possibly the tiny rectangle of the cursor alone. 

Do you think this could be where some of the performance could be gained?
I feel like "selection" is great speed, but the typing is a bit too uncomfortable for me. 

Thanks,

Ryan
