Right off,the OP's description sounds exactly like day one on X2[sending reports] BEFORE the "Quick Fix"??,and X2a includes this,so..
Yeah Iv'e had weirdness,but I set it to save every 3 changes or whatever,but some days,absolutely nothing goes wrong..nada,so I don't even consider going back to X1d expanded.
To be honest ever since using a great performing,for the price here[32 samples 8ms Round Trip Latency Measured Properly with this:
http://www.oblique-audio.com/free/rtlutility]Native Instruments KA 6 USB 2.0 interface,I have had odd things happen-blue screens,ONLY whilst leaving the room,while on the net?,weird long shutdowns,where I have to force shut off,but will fire back up like nothing odd has happenned?
So on I go,and 90% of Sonar time no badness[as long as Ctrl+S,or "save every 3] ,+ this laptop is in a dusty,cigarrette smoke filled enviroment,so I'm just amazed it's all working as well as it is.
I haven't really fired up my faultless desktop due to summers heat[12 days of 40c +!!]and the room it's in is not insulated,but will see,when we experience autumn,and maybe be[?] surprised,as nothing EVER went wrong under X1c,d on THAT machine,and I always only have 64 bit installed.and 32 bit plugs[the few that I actually use]run fine wit the "standard" bit bridge[teleport server]
