Thanks for your interest. The application is "Simplex History Recording Terminal". It monitors all of the alarms, troubles that come across our Fire Alarm System. I have two such units with multiple terminals attached. The system functions fine with Windows 98. I have had the system working with Windows 2000 with some minor problems. I examined the desktop problem and the windows explorer problem a little more last night. When I have windows explorer opened the "file" is the only part of the status bar that doesnt function properly I just dont get it. I have had the system working like it was suppose to with minor problems with the dos application. When I boot up into dos I stop at c: prompt instead of continuing into the program and activating the .exe to bring the program up. When I stop at C: the message says that I am using automatic configuration files and that my autoexec and config files have been renamed autoexec.upg and config.upg. Thest files reside in a folder that windows 2000 created called dos7. I changed the files back to autoexec.bat and config.sys but nothing has changed. I moved them to the c: prompt like the original app would have them and still nothing. I searched for the dos ,exe in windows and could not find it anywhere. I looked into autoexec.nt and config.nt and found that the dos startup file had been added but still it will not boot up into the program. I changed the default at bootup so that the dos o/s would boot first. When I get to the c: prompt I can type in the .exe and the program boots up like it is suppose to. With windows being ustable the way it is I am going to reload the dos program and windows 2000 tonight and see if a fresh install on both will help. Thank you for your time on this project....chuck
