TWR are currently waiting for a new manufacturing run of Generations v8.5a to come into stock but we don’t expect to see them before the end of January. Version 8.5a is Windows XP compatible and works on Vista (32bit & 64bit) too. The price is £19.95 (this will work out at about $35) with free airmail delivery. Your existing family files are 100% compatible with v8.5a. TWR provide full instructions, and help if you need it.
