Hi Ross,<div><br></div><div>That sounds a bit strange. Can you start QGIS from the terminal and see what the output is when it locks up.</div><div><br></div><div>- Nathan<br><br><div class="gmail_quote">On Tue, Oct 11, 2011 at 10:19 PM, Purves Ross <span dir="ltr"><<a href="mailto:rmpurves@ntlworld.com">rmpurves@ntlworld.com</a>></span> wrote:<br>

I put a lot of work into a project using QGIS 1.6 but it won't open in 1.7. The layers all appear but then the screen freezes as though QGIS is rendering the resulting map forever.<br>
<br>A bit of googling revealed that there was a bug at some point which required the placement of 'gdal' between all <provider></provider> tags in the project XML file in a scenario like this. However, I tried this and it didn't work. I also have read various posts that say the use of 'on the fly' project appeared to cause problems going between 1.6 and 1.7. The project in question does indeed use on the fly projection.<br>
<br>As a final note, I have an ECW raster layer in this map that requires the modified GDAL to work. I thought that the crash might be to do with the upgrade having removed my modified version of GDAL. I therefore recompiled it all and have checked to see that my version of 1.7 can now read ECW files and it can (when they are presented a a fresh layer and not as part of the problematic project).<br>
<br>This is a really, really important project to me and I do need to get it back if at all possible. Please can anyone help?<br><br>Very many thanks!<br><font color="#888888">Ross Purves<br>
