Print Screen tool

Hi,

i want print some messages directly to screen and not to Journal.

I use following function. But sometimes it works well, sometimes not and in all cases messages are disappearing after few bars. I want that messages are shown until i call again "printScreen".

void drawFixedLbl(string oldObj, string objname, string s, int Corner, int DX, int DY, int FSize, string Font, color c, bool bg=false)
{
   if(ObjectFind(objname)<0) {ObjectDelete(oldObj); WindowRedraw();}
 
   if(ObjectFind(objname)<0) {ObjectCreate(objname,OBJ_LABEL,0,0,0);}
   ObjectSet(objname,OBJPROP_CORNER,Corner);
   ObjectSet(objname,OBJPROP_XDISTANCE,DX);
   ObjectSet(objname,OBJPROP_YDISTANCE,DY);
   ObjectSet(objname,OBJPROP_BACK,bg);     
   ObjectSetText(objname,s,FSize,Font,c);
}
