Bug Report: adding frames loses everything
I came across this when trying to add multiple frames.
If you right-click a horizontal frame and select add->horizontal frame, no frame appears. If you then select the frame again and try to add a frame from the drop-down menu the page turns blank. Pressing Undo does not help and if you happen to save the file, everything is lost.
The bug appears to work with any musescore file.
My musescore is version 220.127.116.1149 and it is running on windows 10.
I'll test with newer version as soon as I can.
