We've heard from three patrons who use USA Datanet as their ISP. They can't connect to the iPac. All three say that they could do it before but suddenly they've been locked out. I contacted USA Datanet and they sent me the message below. One of the patrons tried this and it worked. If someone calls with this problem, please find out if they're on USA Datanet and if they're using the accelerator program called Propel. If they are, give them these instructions.

Other ISPs use accelerators that can also interfere with iPac access. For more info, see Troubleshooting for the Online Catalog.

******************************
Some of our customers are running a proxy program called Propel Accelerator. The program by Propel Corporation uses port 8080 by design. As we are not able to make any changes to the program, customers do have the option to turn Propel off during browsing. Please the instructions below.

To Turn off Propel:
1. Close all browser windows
2. Start > Run > USA Datanet Accelerator > Stop USA Datanet Accelerator
3. Click 'yes' on pop up warning.

To turn Propel back on:
1. Close all browser windows
2. Start > Run > USA Datanet Accelerator > Start USA Datanet Accelerator
3. Open browser
