I finally got it to work. It seemed to be a problem with the CM93 charts. My original CM93 charts are on a flash drive. Both the Windows 7 and XP computers
will not recognize the charts on this drive. I copied the flash drive to the XP hard disk. Didn't work. I then copied the charts on the Windows 7 hard drive (which originally came from the flash drive) on to a DVD
. The XP computer wouldn't recognize the charts, more freeze ups. I copied the DVD
to the hard drive and success. It works! Does OpenCPN like to have the charts on the same drive as the program?
So, everything is working.
