Using Vista Home Premium. Very impressed with ESS thus far after having it installed for about 12 hrs. Flawless installation after uninstalling Nod32 v2.7, deleting left-over files & cleaning registry prior to installation. Very lightweight, not CPU intensive. The only problems I have had so far is getting FTP to work despite opening port 20 & 21. Also, when downloading from web with Getright download accelerator, it slows my downloads to a crawl, & eventually stops the downloads altogether. Anyone else having similar problems?
