MCP speed change after changing sound volume

[captain_alligator]

Hi there, I found a weird bug today when cruising in speed control mode at M0.74 (I didn't have VNAV because I hadn't punched in the STAR at this point).

I opened up the preferences window, adjusted the sound volume, and closed the menu again. A short while later I got the stall warning, the MCP speed had changed itself to 01. This was reproducible - every time I opened the preferences window the MCP speed changed to 01 and I had to drag the setting back up to 74

Excellent - finally someone found out how to reproduce this - I will try myself and add to the list immediately!
