D12 suddenly changes made in design do not take in runtime

[Fudley 0]

Delphi 12. Project was working earlier today. Don't know what changed, but now, for instance, if I put a button on a form it doesn't show up. If I put a showmessage at various points like formactivate - nothing happened.

 

Did a system restore (windows 11) to yesterday - same problem.

 

Any ideas?

If you put a break-point on that line with ShowMessage it will stop? If yes... step into and see what next.

But it is into dfm? Do you see it at design time or only at runtime is missing?

That's a good point. I need to look at the DFM.
