If this is the behaviour of different versions of builds, then perhaps this would be a good product suggestion for the developers? yyao, I see you are from that group. Would you forward this issue to your group? I don't have a way to test it on different builds, so can't help too much here.
I have a screen record of this strange behavior. And an other bug: The scope trace is not that i was selected on the inputs.
The free codec for the video is here: http://www.compression.ru/video/ls-codec/screen_capture_codec_en.html
Thank you very much for taking the troubles to take capture the video. I was able to reproduce this bug by placing junctions on nets. This defect has been fixed and will be in our next major release of Multisim. However, we cannot release this fix in time for our upcoming maintenance release.
I am looking into the oscilloscope trace colour problem. I could not get the same results as you in Multisim 10.1.357. Would it be possible to ask for the design file or steps to reproduce this behaviour? Does this problem happen to 2 channel oscilloscopes as well?
Thank you very much for your help.
