Jerry, thanks for the response.
Based on your comment I reinstalled, and this time I got an error relating to my video color depth. I switched it to 16, and restarted the program. It seems to use about 60% CPU on my old Pentium III 750 Mhz, but it is working now.
If you don't mind, I would like to ask another question: I am investigating to see if this tool could be used as a front-end to a business database application (i.e. sales force automation). The application would have many users accessing it each with their own context. And wireless or browser devices would be the I/O method feeding Hal.
Assuming that I would be building the front end interfaces from the various devices, and reducing them to the appropriate input level for Hal, is the kind of thing I have described doable with this tool?
Thanks again for your help.
Phil
