Day trading pre-market open August 28, page-13

Hi guys, also before the day gets busy.
My Viewpoint keeps crashing, I have it running on a second screen, use Firefox as my browser and run Windows 7 pro. Use an Otus dongle for internet as no NBN where I live.
It crashes at least 10 times daily and even though I get the option to restore the tab, I still have to log back in to Viewpoint every time.
It has only started this recently when I began adding multiple charts.
Also it refuses to detach a page to transfer to another screen, but will let me do that with individual widgets.
Any suggestions please guys?
