I tried that.

After adding over 2000 pushpins a 1.73HGz laptop with 1 GB of RAM and 128MB ATI card would take forever to refresh the screen.

I guess MP is not really suitable for my purpose. A dissapointmet because I thought dropping pixels on a map's canvas would be a pretty basic operation one might need.

I'll try to ask around Delphi developers if someone has an idea how to write to MP's canvas through Windows API

Thanks for your help.
