NAV 17.8.0.5 crashes my laptop. Folder {NAV_prod_UPG_1.5.30_18.1.0.37} creates under C:\Documents and Settings\All Users\Application Data\Norton and dumps placed under it.
I installed NAV 17.8.0.5 on XP PRO SP3 os. it creates more than 7 GB under above folder. Not able to attached the dump, since it's size is 5 MB after zip.
