I have a few rad RadButtons in a sequence. I have defined them with custom images only.
When I click or hover, the button appears to either grow slightly or is offset by a few pixels.
This causes content to the right and below to shift and it is quite uncomfortable to see.
I've tried to align the buttons in a table with fixed row height and width about 4 pixels wider than the buttons to see if it would absorb the slack. Unfortunately even the table cells shift.
I've not seen this before, and it does not happen if the same buttons use text in place of images.
