I've been recently posting to the list regarding an issue of Gramps
freezing when using the fan-chart. Eventually, after identifying
this as a bug rather than a user error, and taking Paul's advice on
logging it as a bug, I saw that there was a bug-fix in the recent
release of version 4.0.4.
I have now upgraded Gramps to 4.0.4 and you may be interested to
know that the upgrade has fixed the bug.
I can now move around freely in the Fan graph view and use the
sliders without the program freezing.
My thanks to all who have provided me with advice in these early
days of using Gramps. Much appreciated.
