In case it hasn't been noticed before, the tables in both the skill planners and calculators don't display correctly when opened in Apple's Safari Browser (PC edition). This bug may not carry through to the Mac version, though i assume it would. Instead of the descriptive text in each row being displayed horizontally (so it reads left to right), it is displayed vertically, creating new rows as it goes so that each cell contains one character. This results in the table overextended and undefined cells being displayed. I've had similar compatibility problems with Safari with my own sites, so if you figure out the problem, please post your solution.
