Lyx - error: cannot delete temporary directory

[vsharma]

I am using lyx 1.3.0 cygwin winxp professional
This has been reported in this list before
I have noticed the same for some time but it was not a great problem as i 
did not get a complete crash and the files were reusable and it was more 
like a windows nag
I have not noticed any specific behaviour that causes this
Has there been a solution to it now?
The error persists on installing 1.3.1 as well
