Unfortunately, I don't have MapInfo on the PC I am at the moment. Sorry, about that. Next time I will be more prepared. But here what I remember. Hope I understand the question right. Just select the polyline with the mouse after that use CTRL+R and all the vertexes should appear. Then click the right button of the mouse and search for the function "edit object" and "split polyline". Than tap over the vertex where you want to split the polyline.

Hi,

Do you know what do you have on line 480 in Win_Regkey.h?

Cheers,
