continues to crash with .NET error first then App crash

[stafe]

i've been fighting with this some time now and finally turned off all security services even after giving NT8 exclusions... then i found an auto-defrag event log in the middle of the night right before a crash and thought maybe that was it so i turned it off yesterday too - but now i'm still getting a .NET 4.0.30319 System Access Violation Exception followed by an Application crash with the typical unhandled exception error - c0000005...
.... today though i just noticed that on both boxes now a security logon event(4624) type 5 occurs at about the same time i'm in the middle of changing a chart parameter or a time or volume parameter where the chart has to completely refresh.... the logon event just has a hyphen - for the transited services definition - so i'm not sure how to tell what service is logging on at that moment - but i've gone back and the last crashes after completely shutting off Malwarebytes on box1 and MSE on box2 have this commonality regarding the type 5 logon during a chart refresh and crash....

Win7SP1
NT8.10

oh, and no errors in either the log or trace.... (that's a first)

Hello,

So I may look into this further can you send me an Event Viewer log. To get the Event Viewer log please do the following:

• Go to the start menu in Windows and search for Event Viewer
• Expand Window Logs
• Left click on Applicaton
• Right click on Application
• Select 'FilterCurrent Log...'
• Change the 'Logged' drop down option to 'Last 24 hours' > OK
• Right click on Application again
• Select 'Save Filtered Log File As...'
• Make note of the save location, Enter a name for the file, and select Save

To forward this information go to Help->Email Support and be sure to include Attn: Chris Jameson in the Subject line, a link to this thread in the body and a check in the box for "Log and trace files" and also attach the Event Viewer log file.
