On opening firefox (which now seems to take longer than previously, an error dialogue opens headed, "Warning unresponsive script" followed by the message, "A script on this page may be busy, or it may have stopped responding. You can stop the script now, or you can continue to see if the script will complete. Script: chrome://somoto/content/tb.js:2977 I am then invited to check the tick box if I don't want to be asked again (of which no notice is taken) I am also invited to "Continue" or "stop the script". This occurs every time I open FireFox, and on opening, for example, a calendar where I must select a date in order to proceed with my Medicare provider claim. In summary, two problems: slow to start up; and the persistent error message. Thank you for your help! Basil Ornellas (Australia) Running Vista
