Trying to break on a WM_LBUTTONUP within a DELPHI app

[Stingered]

Trying to catch a registration dialog so I can RE the keygen algo, but I cannot seem to be able to break on the dialog. It's a Delphi app, and using conventional methods in OllyDBG and/or x64DBG gets me nothing. I've tried hard-code BO in user32.dll and a windows message break point. Anyway, basically just you just load up the open windows handles in OllyDBG or X64DBG and break on the button command. Doesn't work though.

Any ideas?

[edit]

Tried using IDR and it crashes every single time.

Thx
