problem with gMap cacheing in Acedb 4.3

Acedb 4.3 re-introduced the facility for cacheing genetic maps as
arrays in class gMap for fast access and display. There is a bug which
is seen when trying to update the cached version of the map to reflect
changes in the database. This can be done in two ways, either by using
the "recalculate" function on the menu in a gMap window, or the 
"Make gMaps" button in the align maps window (from the menu in the
main window.)

The bug is that using "Make gMaps" works fine to create the cached
version the first time, but will _not_ overwrite an existing cached version
with a new one. The work-around is to use "Recalculate" instead, but
beware that if you do not have write access when you do the
re-calculate, it will appear to work, but silently fail to store the
new version of the map back into the database. The out-of-date version
will re-appear next time you display the map.

This is fixed in the next release (4.4)
