I play here and on the EZ server with no issues. You have not mentioned any details of your setup although it appears from your screen shot you are running in Windows 7, as I do. They only change I have made is I run the eqgame.exe in compatibility mode (XP SP3) and as administrator. I did this to correct some 'smoothness' when logging in and alt-tabbing. You might also try the WinEQ2 tool as I've read it helps several problems when zoning as well as it's other features:
