    Default Err 1400, Invalid Window Handle

    OK this has happened a couple times to me now -

    I am using EFILive 7.5.100, and upon closing the Tuning tool I get two back-to-back error windows saying error 1400, Invalid Window Handle.

    I had that error yesterday too.
    The PC crashed afterward, I thought it was a Windows issue.

    I've seen it too, but I can't reproduce it reliably yet :(

    If anyone can generate a sequence of steps that will cause it to happen consistently please let me know.

    I think the Scan tool and Tune tool have to be open at the same time - i.e. open the tune tool and load a log file, then open the scan tool and establish the cross-window data linking, then close the tune tool. In my case I have one instance of the Scan tool running and 3 instances of the Tune tool open, and when I closed the Tune tool it got all pissed-off...

    Also got an Invalid Floating Point Operation trying to manipulate the 3D chart display with the right mouse button in {B3647}.

    I'm about to post up a new version (later today) that fixes the Invalid Floating Point error. Its a bug caused by incorrect magnification settings on the 3D surface.

    Mine shows 101...

    but in the last few days I have been thru several uninstalls and registry entry deletions (in my attempt to define a particular bug, mentioned above).
