2 problems one with vertices and other with object datablocks!!

Hello everyone i am new to the forum and blender. love the program and already done some modeling but i have a couple tiny niggles that bugging me and i cant seam to find where to fix them. first is i was doing the auto virtex creating with the ctrl and left click and i not sure what i clicked but all my virtexs are now small when the mwesh is in fill mode. see circled pic. and closing and reopening the blend file dont fix it only creating a new factory reset.

second is i clicked on the object data block to chage some properties of a object to select it and now whenever i create a new object the datablock and setting stay for the last one i selected it dose not auto go to the new one?

sorry if these issues have be posted before i have not found anything yet


Thanks andy
