Loading tracks using keyboard

Hey there!
I have a problem, while performing using an external mixer & timecode:
I' ve decided to use my laptop keyboard for loading tracks in players, rather than dragging them using the mouse, but it seems that it can't stand it, because it makes some serious gaps "on air", not good apparently...
I use a 12ms buffer, that worked pretty fine for me till now. Even if I increase the buffer a little, problem still remains.
Using Cross 1.7.1 (tried sync meters switched off or on, doesn't make any difference)
Windows 7 SP1, LG laptop, Intel Core 2 Duo 1.8GHz, 2MB RAM
Anti-virus disabled. Using external HDD.
Any suggestions?
