Lookout 6.7 source code causes lookout 6.5 on two different computers to crash lookout. Is that normal?

[fmclemore]

When I try to compile lookout source code writen on version 6.7 on a machine with verson 6.5, 6.5 crashes while compiling. Is there any way to aviod this?  The reverse (6.5 source  on 6.7) Works OK

It most likely is because a feature is not backwards (forward?) compatible.

We develop in 6.2 primarily to target everything higher.

In 6.7 the Panel definitions, the last two items before the first object are:

yes, no,

remove these (go back to the comma before 'yes') and it will probably compile under 6.5 (look at a 6.5 panel definition for reference).
