I tried to transform from EPSG 32633 (WGS84 UTM 33) to EPSG 4326 (WGS84), then I tried also from EPSG 32633 to EPSG:3004 (Monte Mario / Italy zone 2) etc. All tests were carried using standard EPSG codes, on different computers (O.S.: Windows XP), different versions (1.10 stable, 1.11): all caused crash. Furthermore, the interface doesn't allow to chose the transformation (for example NTV2 grid), while gdalwarp allows it. > > The whole reprojection engine in gvSIG really needs an > update.

I hope soon, not for me (I can use directly FWTools), but for novice users and for the completeness of this surprising gvSIG package.
