Hi guys,

Peppe just did it what I was going to say, with his last email: Pirol 
plugins creates already such folder. I think it came from the attribute 
cacluator, and maybe some display tool (raster?). So first step may be 
to find that variable and set it to only .openjump.

Also Sextante creates temp files in the general tmp folder. But as Ede 
did outline: OSX & Linux clean this folder automatically, while Win 
users need to clean it manually once in a while. So when I implemented 
functions in Sextante that generated temporary files, then I also 
implemented routines to delete those - most of of the time (and only 
necessary for win).

cheers,
stefan
