[ltk-user] reader error using menus on OS X

[Phil Armitage]

Hi Zdenek,

I hadn't realised exactly what was triggering it but now I try what
you say and the problem is completely reproducible.

It sounds like this patch would be very useful. If it's something that
can be 'fixed' at the LTK level then I'm sure Peter would consider it
for inclusion in the library so please do send it to the list.

Many thanks!

Phil
