I have MS Office Picture Manager SP3 (11.8161.8172). The zoom + and - buttons do not work when I left-click them with the mouse. But I can drag the zoom slider by holding down the left mouse button. Any idea what the problem might be with the zoom + and - buttons? More importantly, any idea how to fix it? I am sure the zoom + and - buttons worked in the past. But Pic Mgr is not something that I use frequently. The buttons might have worked before I installed SP3 and not afterwards. But I can assert that with impunity.
