Enhancement

[James Burrell <jim nanodyne net>]

I just started using Dia-and I immediately saw an area that could be 
improved.

I was looking at the samples.  I opened a sample by navigating to that 
folder-I looked at it and closed.  When I tried to open another sample 
diagram, I had to navigate to the correct folder again.  You should 
remember the last used folder.  I am running on Windows XP.

Thanks.
