[Qgis-user] Project takes very long to load

Juergen, Andreas,

I loaded (waiting... watiting...), saved with a "_pan_1.1.qgs" suffix,
closed and re-openned the project. It still takes _too_ much.

But, it might be (also) another issue? This project loads a grass-raster
rgb composite  (20888276 cell count for _each_ band) and gives in the
terminal some Warnings [1].

I just searched in my *_pan_1.1.qgs files and there is not a single
"key" string.

I' ll try first with another very BIG project (mutltiple grass
rasters-vectors, shapefiles, styling, etc.).

Thanks, Nikos
