[GRASS-user] Grass Novice in Trouble

I appear to have broken Grass

I am using Grass 6-4-4-1 on a windows 8.1 machine.

I have used Mapinfo in the past and spent most of today learning the ropes.

I have managed to load OSGB data and create and modify maps, but as the day has gone on the display has become slow and unresponsive.

I thought this may be because I had loaded too many large layers, so I created a new mapset with the plan of zooming to my area of interest, making it a region and only loading the parts of the maps within the region.

Even this simple two-map mapset wouldn’t display – it seemed to be refusing to zoom to the map, or thinking it was outside the region.

I have obviously tried fiddling with map settings and regions trying to get my blank screen to show a map.

Now, whichever mapset I chose (including the demo mapsets) I get the splash screen (with the ancient map), the main screen appears for a fraction of a second, and then both disappear.

I have tried restarts and even a full reinstall, but I can’t actually get into the program.

Can anyone think what I have broken… at the very least, is there a way to ensure every single ini file/registry key etc. is cleaned out so I can start completely from scratch again?

All help gratefully received.

Regards

I have done a complete reinstall, following deleting every grass-related folder and my install of Python.

It now works, but it is refusing to do a complete refresh of the map display, always randomly leaving some vector maps out. Neither ‘Draw Map’ nor ‘Render Map’ appear to cause anything to happen.

Could this be because of the number of layers (~20)? I have limited map import to my region of interest, which does cut down the data size a lot.

Is there a way to force a full redraw of the map display?

Regards

No idea what's going on, could you install newest GRASS 70 and try again?
http://wingrass.fsv.cvut.cz/grass70/WinGRASS-7.0.0svn-r63215-1147-Setup.exe

For vector maps, you might need to rebuild them with v.build.all because
there is a change in vector format between grass 6 and 7.
