Yes, it can happen if the second click happens in less than 60
milliseconds. Are you that fast? The illume keyboard also has some
inertia and this can make things worse => I could reproduce your
problems typing "sad". I reduced this interval to about 15ms and
things work better => I can type "sad" now with no (or much less)
problems.

Thanks a lot for your tests. I'll prepare a patch and it would be nice
if you help us testing again (I can provide the patch and a compiled
kernel). If you do not have trouble typing "sad" with this new kernel,
I hope you can type "happy" and send a screenshot to us :-)
