Hi there.
I think that you will agree with me ,that Vegas 17 was perfect regarding the menu tabs.
After Vegas 17, even today with Vegas 22 the menu tabs remains small on some installations.
I use Vegas 22 on two computers.
On PC -1 the menu looks fine.
On PC -2 the menu looks tiny.
Check the next photo.
I know that this problem was mentioned on many-many topics in the past, without the developers do any change on the options (or advanced options) menu.
Before I create one more topic, be sure that I have try all your advices/suggestions.
