OK...this seems to work but not sure why ....updated Display Configuration to activate all parts
I added the ASM file name to the list...need to recheck the default settings....and why it happened one time
I was thinking that inactive was the default for openeing assemblies. Not sure if the option was there, but on your Open form, click on an ASM file but don't open yet...
If I remember my V20 correctly, in the lower right might be some settings to open all parts active and you may also find a button to "Save as Default". Clicking that will force SE to always activate the parts when opening.
Later versions have some configurable "size" based options to control this differently for small, medium, and large assemblies.
That seems to be it. I went to OPEN the ASM, clicked on it (not opening as you noted), changed buttons to ACTIVATE (as needed) in that window pane, then dropped down to CONFIGURATION (same pane) and set it to "default"...seems to open active 4 times in a row, including restarting V20.
Thanks so much
