MS4 Issues I've noted

Windows 11
I'm going to assume these are already known and intended for correction in the next release, but putting them to print just in case.
>When entering System text & Staff text, CTRL+B does not make the text bold (though bold works from Properties).
>When entering System text & Staff text, CTRL+I does not make the text italicized (though italics works from Properties). CTRL+U, on the other hand, does provide underline.
>Although I have them set in Shortcuts, @, #, $ (shift-2, shift-3, shift-4 etc.) do not add the interval below the selected note.
>Appending measure at the end of the score, one must click the "OK" button twice. Also, hitting the keyboard enter/return key should do the same thing but does not.
>When entering lyrics, there are very long delays when entering "-" and "_" between syllables and words.
>After adding a slur, in MS 3 hitting Escape would unselect the slur but select the note the slur attaches to. This does not happen in MS 4.
>Special Characters- I changed the Special Characters shortcut from Shift+F2 to F2. However, attempting to use F2 the Special Characters window would not appear. I was able to change the shortcut back to Shift+F2.
>Preferences menu- Clicking "OK" would sometimes be ignored, or maybe had such a delay as to cause confusion.
Plus side: the attached score reduced in length by over 10 pages from its MS 3 version.
I haven't tried the playback sounds, but looking forward to it!
Overall impression- other than the learning curve at my end, very pleased! Thank you!
