I've been trying out the new TWS beta 875 (started with 875.0c and now at 875.0e). For me, View > Account the first time brings up a window saying an error has occurred.... asking if I want to send error report to IB (of course, yes). Then after that, View > Account does nothing. If I delete my settings, I can get back to the error dialog. This all is working great in 874.4. Anyone else seen this? CS suggested a bunch of things... deleting settings, deleting java temp files, downgrading to jre 1.5.0_12. All to no avail. Beta 875.0e and my Paper trading account work fine for View > Account. Just my live account that it won't work for. So it must be something about my positons, or maybe about Portfolio Margin. I know, it's still beta. But that CS has been unable to replicate the problem -- worries me that this will get released.... eventually 874.4 will be phased out..... and I won't have a working View > Account!
