A couple of very minor problems I have noticed:
In the Mac version:
For some reason Jaikoz always wants to move with me when I switch desktops in spaces. Normally you have to click and hold the window when switching to bring a windw with you. But Jaikoz will come along randomly if it is the active window, or recently the active window, or anytime really. I don’t know if this is Java or if you can fix this or what…
Option-A is usually select all. In Jaikoz it is Control-A.
