auto context menu bug in 1.6rc1?

[James Sutherland]

Kudos to the development team for a fabulous 1.6!  I particularly like  
the word completion and math macro features.

Forgive me if this bug is already well known, but the context menus  
for math, macros, and tables all do not appear when those environments  
are active.  I can turn them "on" but then they are always present.  I  
really liked the "auto" feature in 1.5x, but it seems to be broken in  
1.6rc1.

I am running a Mac OS X 10.5.4.
