- My shareware program, AppSizer, does something very similar. Since
- it's a INIT/Control Panel, I added one more twist. In addition to
- simply flashing unregistered copy in its windows, it also puts up
- a message once a month that reminds them of this fact too. This extra
- prompt will often remind them even after they get used to the unregistered
- user message in the windows. And a number of my registed users mention
- that this is what reminded them to register.
