cvs update quite strange

Hi! When I do a "cvs update phpdoc", or only a "cvs update phpdoc/hu/functions", my machine starts sending an extreme amount of memory somewhere, and does nothing to update the CVS files on my computer. That crappy CVS.exe sent 2 megabytes of data, without updating anything... That takes somewhat long using a modem, and I can't see anything worth this time, as nothing really happened to my local files... I have the latest virus protection software for win, and only CVS is working that strange, so I don't know what's up, but I am a bit angry, as I cannot do any work on php CVS stuff... Goba
