Possible 3.5 Beta bug?
Maybe this has already been noted, if so then apologies.
MS 3.5 Beta, Windows 10
The window in the lower left of MS that provides info on whatever is selected (if a note, then Note; Pitch; Duration; Voice; Measure etc.) stops responding after about 5 or 6 selections and the content continues to display what it locked up at, even though something else has been selected.
This happens with every score, every time.
