Hello,

it would be really good if you could provide some more info:
-Does it only happen with komodo?
-How did you install it? It seems to outside regular package repositories
even on Linux based distros. What steps did you take to make it run on
FreeBSD?
-Bug report mentions moving the window to another workspace, here you state
it happens a few seconds after launch. Which is it?

Best regards
Andreas
