Hello, we have following problem: There are some packages for R under Windows, which we can't completely download (in R and Browser). The downloaded file is 0kbyte. We know that this problem is caused by our Firewall, but we do not know why this happens. There are no error messages and no entries in log files. Example Package:gahgu133acdf Url: http://www.bioconductor.org/packages/release/data/annotation/html/gahg u133acdf.html If I delete the rdb-file in this zip, then I can download this file without problems. Maybe someone heard about this problem. thanks, Jerry
