However, having done some Internet work, the next time I clicked on the screen icon, I got the same message - Application running - although my modem lights had stopped blinking. But using the lower toolbar icon, it worked as intended, with a record of past data, etc.
Is there any chance that it is running all the time and slowing down my computer? I'm getting 3.2Mb/s max, whereas on exactly the same setup I routinely got 5.2 - 5.5 Mb/s before I switched from Pipex Homecall to Talktalk.
The speed tester runs at regular intervals (hourly, daily, etc).
When the speed test starts, it will begin a small download to test your speed. It is possible that at the exact same time, your connection is being used (such as by yourself). This in effect means the speed tester won't be able to get a full measure of your speed as some of the bandwidth is being used elsewhere.
