After I have edited anything in the file the cursor does not update at "full speed" until after a few seconds.
It might be because I have an accelerated keyboard repeat rate running at 80 characters/second.
While I hold the up or down-key down the cursor does not show its changed position until I release the key. And also the cursor seems to move at a reduced speed.
This effectively makes 1421-1422 unusable for me.
Edit: If I don't move the cursor at once I only have to wait about 2 seconds before editing at full speed again. It seems moving the cursor puts off the background processing somehow and while the background processing is running the cursor isn't updated.
here i am using winXP pro SP2 and in control panel -> keyboard the character repeat speed is already set at 100%, and i have not seen any response problems in VS 2003 with 1422. however i have VA's option to double the effective rate of key repeat turned off.
turning this on and i am still not seeing any delay. i added a variable and for loop to a C++ function, and then instantly used the arrow keys to scroll up and down the file.
what IDE and language are you using? does this effect happen on all files and projects? i am wondering if it could be tied to the size of the file or workspace.
are you using alt_o immediately after making an edit? any macros? any other "odd" things that might be relevant?
A variation of this problem was introduces in 1426. Whenever I start tying a word or press space after a word the editor goes into a mode where it update approximately every 500 ms until I stop tying for a while. This does not reproduce if I place the cursor in the middle of or at the end of a word and type there.
This is in Visual Studio 2005 RC1
Edit: Here is a copy of the program I use/created to accelerate the keyboard repeat rate to a programmer friendly 80 Hz with 200 ms delay.
