#22 charts are not updated (yahoo), interface very slow

[Anonymous]

I have some charts on my chartsy. If I open chartsy the following day, the charts are not automatically updated. Besides that, the interface is REALLY slow. If I try to draw a line, it appears roughly 5 seconds after I moved my mouse.
