Megasquirt Support Forum (MSEXTRA)

I generally use MLV by double-clicking a log file, rather than opening the program then opening a log.

For the last few months, about one out of every 4 times I do this, MLV freezes and I'm forced to close it using task manager. This happens after the program window appears, but before any log data is displayed.

It seems to happen pretty much at random... I haven't been able to find a way to reproduce the problem consistently. I did try launching MLV from the desktop shortcut about 20 times and it didn't freeze so this seems to only happen when opening a log file at launch time.

Is there a log file or something I can grab that might help troubleshoot this?

Oh and this is happening with version 4.2.03 as well as the previous version and probably a version or two before that.

I generally open the same way, but haven't seen that in MLV..

However, I have come across a similar issue when activating the embedded log view in TunerStudio MS Ultra. So I'm betting it is related.
There it seems to be when disabled icons are generated. Seems to be look & feel and timing related.

In TS it was the Night Shade L&F that was triggering it. It would then lock the event thread while loading the icon image. There I explicitly set the disabled icon and that cleared that up. I have a feeling you may be running into something similar..

Your MegaLogViewerAppDebug.txt might show something but probably not. In TS there is a Thread that monitors the Event thread and prints all stack traces if it hangs to see where it is. That was put in when i 1st saw this issue there. MLV doesn't have that yet as I haven't heard of a thread lock there til now. You seeing it implies it may be a common component where I though it was in a TS specific logging UI component.

If you'd like I can look at / upload that file... where is it located?

BTW this is on 64-bit Windows 10 if it matters.

The file is at:
[UserHome]/.efiAnalytics/

It is MegaLogViewerMSLogFile.txt if you are using MS and MegaLogViewerHDLogFile.txt if you are using HD.

What Look & Feel are you using?
