No problem.
I also have a thread that I started in the Upgrades section.
There is a reg edit to help with getting the red/end key to react faster, but I've found that even that isn't consistent.
I had found a reg edit to make all the keys faster- it did work for a while, but I couldn't find it again after I did a hard reset a week later.
I just reflashed back to a 19176 build of 6.1- the 20273 was nice, except I couldn't get it to sync after the first time I did it!
