[Anonymous]

Lot of times (randomly) we get following error message
when we try to access any file "Unable to access file
info:NULL error" I tried to run gui.bat and the error
details on console are as follows -

I am running client on windows 2000 XP. the problem
clears on its own and then reappaers.
Any suggestions/solution?
