In lookout 6.5 and 6.6 I found a little (or greater, depending how much expressions you have on the panels of your project) mistake.
When you recompile a project using .lks file, the expressions with display type set to TEXT, lose it. And if you need to modify them, you must redefine the display type and set the all the other options of the expression: background color, fore color, font type, etc and RESIZE the expression. The resize is the worst thing to do.
See the attached project.
Thanks to all
It looks like a bug. Thanks for report.
