Base List Box displaying as white text against a white background

I recently discovered that a form in an .odb that I only occasionally use to interact with a MySQL backend started behaving strangely. When I click a list box, I don’t see any options. After some fruitless investigation into the query for the list options and the connection, I discovered that, after opening the list box, if I run my mouse down the empty space where the options should be, they show up as white against the blue highlight, so they’re there, but they’re shown in white instead of the black that the control’s font is set to. This seems like a bug. Anyone have thoughts on this?

Also, my machine is set to the “Dark” theme, so maybe it has something to do with that.

Indeed, when I switch to the “Light” color theme in Windows’ settings, the options show as black text. It’s a bug that I shall report.

I don’t know how it happened, but somehow, the control’s background color was set to “White” instead of “(Default)”, which should have been the default. Once I switched it back, it shows as white text against a dark grey background (the dark grey from the dark theme).
