Are other users having the same problems as I am. It seems extremely buggy, to the point I almost can't use it. I tried installing on 3 different computer, all with windows XP home. My main trading computer has only OS, qcharts, stock watch pro, IB's TWS and excel. SWP crashes completely if I try to open ANY chart window. Can't even close the program except through task manager. Symbols randomly appear in my Level 1 windows. And now, worst of all, when I click on a row in a Level 1 window, it changes all my chart intervals in qcharts. I have tried repeatedly reinstalling the software, to no avail. Is this just the way SWP is. Their support people have already told me to live with it and use qcharts for charts. But now with the other problems, I don't think it's usable.
