Thank you. I can see them now. Were you using any keyboard shortcuts?
Because at that point in the game, there is no drop down menu, so I'm confused that you mentioned you were using it. I'm really sorry, but I have no issues at all changing cursor modes, and nobody has ever mentioned this before.
Hopefully one the genius AGS forum members can make sense of what may have happened here. I'm very sorry again, and hopefully we can figure this out.
