[Tfug] OT: Lego Mindstorms Help

[Christopher Robbins]

I am a psuedo-teacher at Flowing Wells Middle School, teaching robotics
after school with the Lego Mindstorms kits.  I was wondering if anyone on
the list had experience with the sets, and if they could help us wth a
problem we've faced.  Our RCX(es) have problems with keeping the batteries
in place, and as a result, lose any programs that have been programmed
into them.  The RCX(es) work fine otherwise, but we're wondering how we
can get this fixed or if anyone has seen this problem before.

TIA
