Why does an unselected object delete by keypress?

[Brian Lillard]

When I create button and label from expert advisor

ObjectCreate(0,"button0",OBJ_BUTTON,0,0,0); 
ObjectSetInteger(0,"button0",OBJPROP_CORNER,CORNER_LEFT_UPPER); 
ObjectSetInteger(0,"button0",OBJPROP_XDISTANCE,10); 
ObjectSetInteger(0,"button0",OBJPROP_YDISTANCE,10);
ObjectCreate("label0",OBJ_LABEL,0,0,0);
ObjectSetText("label0","Label",9,"MQL5",clrLime);
ObjectSet("label0",OBJPROP_XDISTANCE,20); 
ObjectSet("label0",OBJPROP_YDISTANCE,25); 
ObjectSet("label0",OBJPROP_CORNER,0);

Same issue (select object after creation unchecked). Each backspace press causes deleting an object from a chart (in order from the newest to the oldest). It doesn't depend if  the object is selected or not.

Exactly as documented. Perhaps you should read the manual.

Thank you, William, for having such a good overview of the manual, and for being willing to share it with others.

That's a pretty stupid feature IMHO. Especially when using objects for editing. But this is not a comment on William, but on MetaQuotes.
