Having just finally upgraded to 1.5.2 (1.5.5 will not run on my system so far)
I find that the Zoom function which in 1.4.6 was managed with keystrokes CNTL + / - has been disabled
in favor of a less flexible selection function in the View menu which allows only the increments
75%, 100%, 200%, and requires accessing the drop down menu instead of the convenient
keystrokes to change the view size, which worked before. Hope this keystroke function can be put
back in, in the future, and if possible with more gradations of size available.
