Middle-clicking while the context menu is open prompts an unhandled exception

[B00ie23]

Problem This was encountered by accident, when right-clicking to open the context menu, simply middle-clicking while the menu is open brings up an unhandled exception.

Steps to reproduce

1. On the configurator, right click any Soundfont to open the context menu.
2. When the context menu is open, do a middle click.
3. The unhandled exception message should appear.

Expected behavior To be honest, I have no idea what the intended behavior is supposed to be. My guess is that middle-clicking isn't supposed to do anything, see additional context on the bottom.

Environment

• Operating system: Windows 11 Home (x64)
• CPU: AMD Ryzen 5 3600
• RAM: 16 GB
• MIDI application: None
• Version of the driver: 14.6.13 (PR81)

Additional context This does not appear to affect the configurator or OmniMIDI as a whole in any way as it seems to behave like nothing happened when you press continue.
