@p3c0 Thanks for the suggestion. Sorry about the delay in replying.

I can achieve a good result by dividing by 1.1 instead of 2. Using 1.1 I get blue box just a little bit smaller than the radio button itself.

For some reason if I make the ration 1.01, the blue box exceeds the size of the radio button.

If I simple divide by 1.0, the application fails to get out of bed.

Thanks

James
