OpenMPT v1.17.02.53
Has the bug occured in previous versions? If yes, please specify version(s): Not sure.
Description of the bug: When opening more than one window for the same track (Multiview), MPT crashes when you try to open more than one window in the Instrument tab.
How often does it happen?: Always.
How to reproduce (step by step description): Open or create a track. Choose "New window" from the Windows menu. Either Manually separate the windows or choose one of the "Tile Windows" functions in the Windows menu, so that you can display both windows of the song simultaneously. With one window open the Instrument tab. Now with the other window, open the Instrument tab. (I was doing this to check if the windows updated each other.) Upon clicking on the 2nd Instrument tab, MPT shuts down without an assertion or error message.
