Dice Roller Issues

my dice roller does not roll dice.

All of the options are present on the character sheet, including the dice menu on the left of the character sheet.

Right clicking on weapon attacks brings up the rolling menu as per normal, but no actual dice roll appears when the roll button is clicked.

I've tried different dice sets, with no change.

As interesting item of note, the character image and frame also seems to be effected.

If I clear all of my cookies and cached images, then the character portrait and frame work, as does the dice roller, but only for a few hours.

Any suggestions?

Do you have the Beyond20 extension installed?

If so check there to see if you have Digital Dice rolling disabled within there.
