Use VRocker's VC:MP Server Browser, or set your compatibility on the current one to Windows 98/ME and copy your GTA:VC settings file over from "C:\Users\<Your Account Name>\Documents\GTA Vice City User Files\" to "C:\Users\Public\Documents\GTA Vice City User Files\". Either fix will work, as this is a Windows Vista and higher compatibility bug. SA:MP used to get it too, but they fixed it in a later version, which means it's just old code in the Server Browser itself.
