This exactly, we need a fix for this, otherwise you won't know what's the issue. The last time happened after I checked PC and adjusted up speeds, turned monitor off, went to sleep and when I checked again the morning after, tixati was closed without notice.
Thank you devs.

Check your desktop.
There will be a tixati_log.txt file
Mine said "Out of memory"
Are you using tix 32bit or x64

This time no log was saved to desktop. I'm using Tixati 2.48 x64 Win10 OS.

ditto.  had a crash.  no report prompt or log to desktop.  Win x64

For post #3 and #4 do you know what you were doing when it happened? Or was it unattended crash (@)#(* WTH)

If its dealing with specific transfer/.torrent this would be helpful to diagnose/patch a potential remote crash vulnerability, but that sounds unlikely :/
More info is needed.
