Changing the time of a piece of music breaks the display

[kernighan]

If I import a MIDI done in 6/8 time, it is shown as 4/4 time. If I then change the properties to be 6/8 time, much of the UI breaks (including the window to change the properties). If one can manage to get that window closed, the window displaying the imported track is also broken (showing overlaying tracks) and requires resizing the window to fix the display.

A simple 6/8 time signature MIDI import was fine. I think there are other problems.

Let me explain better. I import a MIDI that is in 6/8. The program however sets the timing to 4/4. I then go into the properties via the file menu to change it to 6/8 time so the measures line up correctly, at which point the program windows get all messed up.

Thank you for your detailed explanation. From the screenshot image it looks like there is some kind of problem. But the MIDI data I have can't cause similar problems, so I need real data.

I can't debug it with the information I have now. Additional information required.
