Following the application note at http://dx4win.ad1c.us/appnotes/upgrade.htm I seem to be having a problem writing the 8.02 dx4win.ini file of the preferences. I get the following error message: "An exception occurred! Access violation at address 00405985 in module 'dx4win.exe'. Read of address 4020890E." No file is written. Any suggestions? 73 Ted W4ZE
