Many users of Fast Dial 2.x report seeing a small blue circle at the top left of a Fast Dial Cell

Often the user is unclear how to remove this item, or even what it's function is.

To remove the this blue circular icon all you need to do is to right click on the offending cell, which will take you to the Properties Menu.

Change the value in the "Refresh every" field to zero.

This should have the effect of disabling the auto-refresh function for that cell.

The small blue icon should then no longer be visible.
It's function being to remind the user when the auto-refresh option is enabled for a cell.

It has been mentioned by spillz on Userlogos see
refresh symbol on thumbnails,
that for the user who wishes to make use of auto-refresh for a cell, that it would be a most welcome option to be able to inhibit the display of this refresh button.

While I can see the reason for displaying this button in the first place, it could clearly be argued that for the experienced user, once it is clear which cells were set to auto-refresh, that it would be a most welcome option to be able to hide the display of this button, as it's visual presence is quite intrusive.
