F8 does not work in beta2. This is actually listed as a known issue but the suggested workaround is to use Fn F8 (Function and F8). Unfortunately this will not work on a desktop Mac (such as the iMac or Mac mini) as the desktop Apple keyboard does not have a Fn (Function) key (the MacBook Pro does). The following keys do not map correctly between a Mac and the client Windows XP. Typed on Mac Result in Windows @ " " @ ~ Â¬ (equivalent of Option L on a Mac) Note: this is with a UK keyboard plugged in to the Mac and UK keyboard layout defined in Windows. While the @ and " are swapped and are an error, and both Virtual PC and Timbuktu can make the same error, the above list is somewhat impressive for its shortness. Timbuktu (by Netopia) has a much longer list of incorrect mappings (between a Mac and PC when controlling the opposite operating system), this is despite my having reported this to Netopia several times going all the way back to 2000 [Grrrrr!!! ] Also as mentioned elsewhere, keyboard repeating does not work either.
