Hi there, I got a new laptop with Windows 7 and IB's TWS keeps crashing after clicking around a few times (i.e. after changing something in a chart, editing the Global Configuration, nothing fancy). This happens even right after rebooting and with no other programs running. Never had any problems with TWS crashing in computers running XP or Vista and the laptop seems to be working fine with all other programs, so I'm assuming there's something wrong with my software (java, whatever). My specs: - HP Pavillion DV6 (3151), i3 370M, 4 Gb RAM, blah, blah, Graphics card ATI5470 512 Mb. - Windows 7 Home Premium updated with all security fixes - TWS 911.3 (have to use this version with NinjaTrader - was working fine in the other computer) What I've tried so far: - Upgrading memory allocation to TWS (the C:\Windows\system32\javaw.exe -cp jts.jar;hsqldb.jar;jcommon-1.0.12.jar;jfreechart-1.0.9.jar;jhall.jar;other.jar;rss.jar -Dsun.java2d.noddraw=true -Xmx<b>1024M</b> jclient/LoginFrame C:\Jts trick) - Upgrading Java to 6.23 (had .20 in both computers). What I'm going to try in the meantime: - Disconnect the power cord to run on battery (then the laptop uses the integrated graphics instead of the graphics card) to see if it's the graphics card drivers (I doubt it, but hey...) - Uninstall <b>all</b> java and do a clean install. - Uninstall and reinstall TWS after reinstalling java - Unistall and reinstall the last TWS version Then I'll have to deal with NinjaTrader, which is also crashing (in case this helps or is somehow related). Any help and/or guidance would be much appreciated.
