>We have encountered a lot of "Error Reading File" errors in the last couple of weeks. The error occurs in a lot of different scenarioes (which leads me to think it is not a code problem). Here are some of the cases where we get the error:
>blank for field1=var1
>sum field1 to var1
>replace all field1 with var1

>I read somewhere that this error could be caused by network hiccups.
