PC becomes very slow when disconnected from internet in remote mode.

[MS-Jahan]

I have used your tool and it's a great tool. But when I gets disconnected from internet, my PC where I used this tool gets very slower (after 100 keystrokes of course!) and it becomes hard to input anything from keyboard or move pointer (I am using another PC's keyboard and mouse through lan connection ;-p ). Is there anyway to solve this so that it will continue logging keystrokes offline in the hard drive (in a txt file) and send the keys when gets online?
Or will you kindly re-write your code to solve this problem?

Thanks. :-)
