--- Comment #33 from Adam Bolte abolte@systemsaviour.com --- (In reply to Sebastian Lackner from comment #32)
No registry key is necessary, there is no technical limitation to show the message just once. I'll write a patch later. But the discussion about the warning itself should probably be moved to a separate bug report. Feel free to add me as CC if you're going to open one.
Thanks! Opened bug #38032 and CCed you.
