On the scroll set
hScrollBar = "alwaysOff";
Thanks.
I manually populated the list in this picture (notice the History button on the joinServerGui) :
I could've just added the host + server name to the list instead of the ip as well, but I use getRowTextById and getSelectedId then get the last word for joining. When you press join server, the manualJoin dialog automatically is filled in with the details and immediately connects.
