Calendar question

[Guest guest]

I use my Palm and synch between the handheld, my laptop, and Judy's

desktop. Once in a while (rare and erratic) a calendar item will

disappear. Once in a while I'm not in the office and Judy and I both

make an appointment for the same time slot in the future.

So... what program out there would give me real time calendar

function in my hand, on my laptop, and for Judy, that is not prone to

the rare synch mishap?

Thanks
