For any of you that own some of the Tube CAD companion programs, be aware that Tube CAD and Audio Gadgets are old enough to be compiled in a 16bit and won't run under 64bit Windows.
However, they will run quite happily under a 32bit OS such as WinXP running in a virtual machine. I am using Sun VirtualBox (free for personal use) to run XP in a VM and Tube CAD runs just fine that way. There is one thing that must be done and that is to install a printer, any printer, in the VM. Tube CAD checks for a printer at start up and will throw a GPF error if one isn't found. Thanks to John Broskie for cluing me in on that fact.
