Change to User.VisMask overwritten when shape is modified...

[cjleahey]

Guys,

I am trying to change the date format on a Bracket Interval to display as "8:30pm Fri, 28 March 2014" (using the following mask ="{{h:mm am/pm ddd, d MMMM yyyy}}") for the User.visMask property.

This works fine, but as soon as I change the date for the interval using the "Configure Interval" dialog the mask is lost.

I can find no way of persisting the change?

Can anyone offer any advice?

Thanks
CJL
