autocad problem..(selecting object)

Hello! mga CGPians hingi sana me ng tulong regarding sa autocad..kasi recently na notice ko may nag bago sa pag pick ko ng selection ko..for example pag ng move ako na command..command "m' enter then usually ang pag select ko ng object drag lang from right to left. then supposed to be dapat mag dash sya para malaman na selected na sya..pero ung sa case ko walang nangyayari..nababasa ko lang sa command line na selected na ung object na un..ok lang naman sana kaso minsan nakakalito kasi akala ko d ko pa na pick ung object.yon pala duplicated na..any suggestion..sana d kayo nalito sa explanation ko..thanks in advance...

galing! nice one sir! bagong kaalaman nanaman

galing talaga. kaya basa basa lang dapat sa system variables editor para sa trouble shooting. express menu/tools/system variables. o kaya sa command bar type sysvdlg
