Hi,<br>
<br>
I've have experienced recently on several occasions a strange
behavior of qGIS with what I think, memory. I cannot reproduce with
a basic example, I need my whole project to make it happen.<br>
<br>
I'm working for a conservation project and I've got a set of
shapefiles with streams, tracks, contours .... and our traps and
baitstations (we do pest control). I'm currently trying to make maps
of bird census for our end of year reports.<br>
<br>
Most of the data I get are from GPS, which is easy to handle (either
the gpx file of by importing a csv file). But I also have to create
shapefiles (points and polygons) to place bird sightings and draw
territories. These files don't have any columns for GPS coordinates,
as I draw the points or polygons using field markers (sighting next
to a trap or near a track). So I create the shapefile, fill it in
with a few data and save it, then fill it in with more data.<br>
Everything goes well until the moment I save the shapefile again. It
is saved but the points or polygons get all mixed. They are at the
good place but not for the bird they were supposed to represent!<br>
<br>
I spent 2 days trying to understand what was possibly wrong and the
only way I managed to make it work was to create a new shapefile
each time I saved new data. <br>
Unfortunately, after 4 or 5 times I saved files, qGIS starts 'not
responding', a lag which the first times is some seconds and becomes
several minutes and then I have to reboot the computer.<br>
<br>
Is there a way to trace what is happening? Nothing appears in the
log messages nor in the windows event logs, it seems.<br>
I'm using windows 7 pro 64bits , qGIS 2.12.1-Lyon code revision
16760fd. Same problem with 2.13.0<br>
I'm not connected to any databases, just working locally, no WMS
connection and qGIS takes already ages to load the project (~3min).
It never happened to me with the old versions like Dufour.<br>
<br>
Any hints about what to check, look for would be much appreciated
...<br>
Cheers<br>
Laurence<br>
