I just thought I would let you know that I am using HotPotatoes v.6 with Linux through WINE (windows emulator) and it works really well. The last implementation of WINE did not allow the dropdown menus to work on HotPotatoes ... however, with the latest release of WINE, the dropdown menus all seem to work!!!
I just thought I would mention this just in case some were using (as I was) HotPotatoes in Windows without realizing it works with WINE. No need to boot in Windows. (Note: I am using a dual boot machine Mandrake Linux v. 10/Win98SE)
FYI ... FileMaker Pro also works quite well with Linux!
