I encountered a major problem that I dealt directly with Lee on (as I could not source or explain the problem exactly on the Forum), Lee sent me a copy of 2903 64-bit pre-release to fix the problem which was great.
However, today when I went to strike-through some text, using the formatting shortcut, I noticed it di not work. Neither did Bold, Underline, Italics. My other shortcuts all work still and when I selected the icon to do the action on the Format Toolbar, it behaved properly, but trying to do the same with the formatting shortcuts in the editor did not work (nor do they in Notes)
Not sure if this existed in 2902, but probably not or I probably would have noticed it sooner.
