Hi, i have searched the forum, seems my issue is not reported.
I had first experienced this with 4.4.4.2000 (previously i was on a 4.4.3.x), and now i am on 4.4.4.3000. I run winXP sp3.
Sometimes (between 0 and 2 times a day) i start the browser, it launches properly then after a few seconds (< 5s) it closes itself.
The content of the browser does not seem to matter (i.e. reload last websites opened or just bare quick access window).
In general, once the issue is there, i can't get away with it. If i relaunch the browser many times, it closes the same way as many times.
In some cases, if i wait a few minutes before trying again, i will launch and work properly, but often the only solution is to close the session and log in again, then it will 100% launch properly.
Except for this behaviour Maxthon is very stable for me, even for hours of browsing.
It doesn't behave like a crash, it just closes (there is not popup message, nor any other message when it happens to launch properly again).
I have verified in active processes before the launch and after the close, there is no Maxthon zombie thread running in the background.
I have tried also to disable ABP extension for 4 days and haven't noticed the issue, so it may be related to adblock, but considering the frequency of the issue, i could also be luck.
