The Voyager is a good modem, I don't think that is causing the problem. Here are a couple of things to try. Let us know how you get on.
1)Log off AOL and go to your "Start" button, click on "search" and include hidden files and folders Type in the following.
Click on the search button and all files that are found, "Delete". AOL will rebuild this folder for you next time you log on.
2)Open the AOL desktop but don't log on. Look to the toolbar and click on "Settings" then "Preferences" from the new window that opens click on "Fonts/Text/Graphics" look to the lower section of the new window and you will see a box with the number 40 in it. Reduce this to 5 save and exit back to the AOL desktop.
Close down the desktop and reboot your PC. Open the AOL desktop but don't log on. Do as above but this time take the number 5 back up to 40. This will rebuild your graphics for you. Exit to the desktop and re-boot your PC.
Open the AOL desktop and this time log on. You should now find it will work fine and close down instantly when you log off.
Print this off as a guide before you do the above and if it has not helped then please post back to this thread and we will try again. There are a couple of "Hotfixes" from Microsoft that when you down load them sometimes overwrite your AOL settings and need to be removed. Only do this though if the above fails to help.
Good luck. j.
