Bug: Still Issue with Rhino flickering and hiding when using toolbar

i believe it was reported probably i reported it myself but cant find it in an eye blink, since this is still happening i just report it once more.

the issue is that sometimes when i select tools from the left toolbar then click into the viewport and with the command still running Rhino suddenly completely while the focus is still in Rhino, getting back the Screen is a nightmare.

i have the feeling it has something to do with the tooltips getting hooked up, since this entire issue only happens with tooltips stuck. i cant reproduce is always, but once it starts it does not stop. till i open a new file, or whatnot.

any further thoughts on that?
