I know this is not normal, but version 22.214.171.12420 crashes with Wine in Linux. The latest stable portable version, 126.96.36.19996, runs fine. I don't know if this is a problem with my Wine installation, but I've never had issues with HeidiSQL and Wine in Linux, it run just fine. I'm attaching a screenshot of the crash (if it's useful in any way).
Thanks and keep up the great work!
