Session Manager not in taskbar

If I start Heidi and the Session Manager show the Session Manager does not show in the taskbar making it impossible to see that HeidiSQL actually started if you switch to another application right after launching HeidiSQL

Not the case here in r3832. Which build are you running?

1) turn off "auto reconnect"
2) exit heidisql
3) launch heidisql

I'm also on r3832

Well I did the same to test that, but I have a taskbar button. I'm on Windows 7, probably an XP issue?

I see the same on Win7

Hey now I see it too - the button is there but then disappears after 5 seconds of inactivity. Weird...

See issue #2629
