Search box treating certain letters as message commands?

So here’s a crazy thing that just started happening to me. I thought my keyboard was failing on my laptop… I would try to type in the eM Client search box way on the upper right but some letters would consistently never appear. Letters like N and M, for example.

I also started discovering that some messages in my inbox were inexplicably showing as unread. Or being marked with little star/flag indicators. All of this was puzzling until I realized that as I was typing up in the search box, eM Client was treating some key presses as message hotkey commands… marking emails, moving emails, etc.

What’s happened? This was never like this before. I’m now reduced to having a notepad window running and typing any email searches in THERE then cutting/pasting into the eM Client search box.

I’ve spoken to others at my company who also are having similar issues with their Search box. This can’t just be our machines and no one else’s… what is causing this behavior?

I’ve isolated it further, BTW…

If i start typing in the search box and the suggestions or recent searches menu pops up, THEN is when this awful behavior manifests (and using the “N” key or the “S” key will start marking messages in my inbox or whatever)

If I his [ESC] so that the suggestions box goes away, then I can still type “N” or “S” normally. Until the pop up appears again.
