Bug : Autocad 2015 - Try to launch command when acad not finished to load a dwg.

[AubelecBE]

Hi all.  i load a big plan with AEC_WALL etc.. 

if i try to launch a command. when acad not finished to load or in process of displaying the AEC_WALL :

i keystroke the key 'zoom'  but when i send the ENTER (SPACE) key : nothing.

after that : nothing. i can keystroke all keys except enter or space.

+ the cross-haired cursor sparkle.. --> i can only kill the process acad.exe..

anyone have this issue ?

I Have Acad 2015 with SP1.
