Crud. *&%$##@! I had to replace my laptop and the real deal for one came with Windows Vista. I had heard about how much stuff was not compatible, but once I got it to recognize some of it's hardware, it worked fine.... UNTIL I tried to install my old nav software with all my worldwide charts. It loaded all the stuff fine but it just won't open and says there is a problem with the exe file. Duh. This is an old commercial program that is no longer supported, so I guess I'm just toast. Just an FYI. Rick D.
