Key press delay

2012-02-25 Thread Keith Whaley

Mac OS 10.6.8
iMac 7,1 Fall 2007
SM 2.7.2

When I'm typing a message, either in answer to someone else's post or an 
original for me to post to the list, I frequently find the appearance of 
the letters on the screen lag the pressing of the keyboard keys by as 
much as 3 seconds.


If I ignore that and keep typing, eventually the words will appear, but 
not smoothly, as in a word processor.


I merely want to know why that is. Suggestions welcome.

As one might guess, it hasn't happened to THIS post yet. Go figure...

Can you have an activity monitor running while you are typing to see if 
the OS is off doing something else while the keystrokes wait in the 
buffer?  I had a serious case of that a few years ago that we traced to 
a lot of extraneous re-paints.

I see that too, usually when typing a password;particularly when SM 
gives me an unsolicited prompt for my Master and I don't catch that the 
cursor has shifted to that dialog...like just now.  I'm running the same 
same setup as you, 4G of RAM installed.


Outside of the annoying (and long standing) random SM Master Password 
prompt bug, I generally chalk the keystroke lag up to processor 
overload...or USB arbitration.  How many things have you got hooked up 
and active, and how much RAM do you have installed?


You could always pull up Activity Monitor and give it a watch.
