Internet Explorer and Opera are the only browsers I am aware of that shows the time logged in on one line.
Firefox, Chrome, Netscape, Safari, all show the time logged in as two lines. I honestly have no problem with this. Doesnt bother me at all. This is still a beta build of SMF so perhaps its a bug they are aware of.
Anyone having other problems need to clear their cache and try again. I have seen this problem before but was easily able to get rid of it.
For those using IE6.... well perhaps use a different browser or upgrade is all I can say. It is 3 years old now but I can say ive used IE6 in the past month or so and dont recall seeing any major problems. If a recent change to this forum was the cause of those problems, im not sure if anything will be done to accommodate such a legacy browser.
EDIT: Jesse beat me too it. I agree that with a browser that old I dont seem any point in working to support it.
