[GRASSLIST:5186] newbie question

[Andy Fraser]

hi all:

i've installed the latest cygwin version on an XP pro sp1 box.

when running some of the demo data i'm finging theat i can create temp 
files with r.patch but when i go to display, i get the following error

WARNING:Fail of initial read of compressed file [k059 in andy]
mail: not found
WARNING: unable to open raster map [k059 in andy]
mail:not found
ERROR: Not able to open cellfile for [k059]
mail:not found

i've looked in the andy directory and it does appear to exist.  large file 
in the cell directory k059 in the cats directory etc.

i'm stumped.
permission's problem in cygwin?

any suggestions would be appreciated.
thanx.
