First: Sorry for my English. I hope you undertand me!
I've posted this same message also in delphiarea forum, but nobody respont to me.
This is my problem.
I've extended the TSimpleGraph, overridding the DrawBackground and painting on the canvas a picture... a simple calendar. It seems work well, but when i'm using my new component, on the mouseup event paint blank all background. I saw the proble is on the WMPaint procedure, but I cannot resolve it.
