18552,Host-guest shared-folder stops working and guest hangs,JohnnyG,,"Often when trying to access a shared folder from Guest (Win 7 Ultimate N 32bit, fully updated), the explorer.exe stops responding, the folder I/O stops and Guest becomes unstable (other processes don't stop working, only those dependent on explorer). The only solution is hard reset and try again. 

Sometimes I am able to transfer larger portions of data to Guest local drive, but usually I can't transffer more than 100 files (100s of MB) at a time until the freeze occurs. 

I tried reinstalling Guest Additions, no effect. 

I am using an R console on the Guest (cran.r-project.org) and an R-based data analysis program.
