"Save Graphic As..." suddenly doesn't work

Question

I suddenly can't create jpegs or pngs using the menu. I have not changed versions or operating systems lately, but the method I've used all along suddenly doesn't work.

When I create a plot, left-click on it, then right-click and choose "Save Graphics As..." a Message window pops up with the error message below. Restarting MMa and my computer did not help.

4/17/16 18:41:09 The specified setting for the option WindowSize cannot be used.

During evaluation of In[7]:= Set::shape: Lists {SystemConvertersDumpheight$883,System`ConvertersDump`width$883} and {0} are not the same shape. >>

During evaluation of In[7]:= Image::imgarray: The specified argument {} should be an array of rank 2 or 3 with machine-sized numbers. >>

Strangely, I can still use "Save Graphic As..." to create PDFs.

And Export[] still works:

Export["C:\Users\admin\Desktop\example.jpg", Plot[expr, {x, 0, 3}]]

The plot I was trying to save as a jpeg was generated by this code:

ClearAll["Global`*"];
gau[x_, v_] := Exp[-(x^2)/(2 v)]/Sqrt[2*Pi*v];
f[x_, m_, v_] = gau[x + m, v] + gau[x - m, v];
g[x_, m_, v_] = gau[x + m, v] - gau[x - m, v];
h[x_, m_, v_] := 2*Log[f[x, m, v]/f[0, m, v]] + (x^2)/v + 6 x*g[x, m, v]/f[x, m, v];
Plot[h[x, 3, 1], {x, 0, 3}]

And to emphasize, I'm doing this exactly the way I did it two days ago and for months before that, and this problem just started today. Export[] gets the job done, but "Save Graphic As..." suddenly doesn't work right.

I am running MMa 10.3 on Windows 10.0.10586

Code:

ClearAll["Global`*"];
gau[x_, v_] := Exp[-(x^2)/(2 v)]/Sqrt[2*Pi*v];
f[x_, m_, v_] = gau[x + m, v] + gau[x - m, v];
g[x_, m_, v_] = gau[x + m, v] - gau[x - m, v];
h[x_, m_, v_] := 2*Log[f[x, m, v]/f[0, m, v]] + (x^2)/v + 6 x*g[x, m, v]/f[x, m, v];
Plot[h[x, 3, 1], {x, 0, 3}]

Example:

*.png example

Export["example1.png",Plot[h[x, 3, 1], {x, 0, 3}]]

*.jpg example

Export["example2.jpg",Plot[h[x, 3, 1], {x, 0, 3}]]

Output:
