Windows 7 SP1 64-bit.

I'm running multiple beta versions of mIRC at the same time, they have the separate mirc.ini files in the same folder as the .exe. Each version has 13 connections into my ZNC on my LAN. All connections into ZNC are SSL with a self signed cert, mIRC is set to automatically accept invalid certificates.

Each beta version was started in the order they were released, with the newer versions starting a few seconds later. I don't have the older releases.

//echo -ag $os $version $beta

7 7.61 961 ; Still running, 12 hours.
7 7.61 1001 ; Crashed at 55 minutes and 25 seconds.
7 7.61 1161 ; Still running, 12 hours.
7 7.61 1242 ; Crashed at 3 hours, 29 minutes and 4 seconds.
7 7.61 1281 ; Crashed at 15 minutes and 16 seconds.


7 7.62 ; Crashed multiple times before I started debugging this.


Triggered?
7.61.1001 ; Crashed while znc was reconnecting/rejoining channels due to internet disconnect/connect?
7.61.1242 ; Crashed when joining channels?
7.61.1281 ; Crashed for unknown reasons?


7.62 ; Crashed multiple times for unknown reasons after X minutes I typed something?

Another weird thing,


7.62 from a few days ago: https://www.dropbox.com/s/m18jrg06vbye5ie/mirc-double-buttons.png

Some? of the beta versions did this before I closed out of everything and re-started the testing above. I have not been able to replicate this in the current testing session.

Another user has also reported only the crashing ##mirc on freenode. They are using Windows 7, 32bit, 7.62 using ZNC connected via SSL. Have not been able to get more info from the user.
