Hi,<br>
<br>
<p>Running MikTex 2.9 32 bit, all updates as of 12/1/2013 applied.</p>
<br>
After the latest update, yap only shows a blank window with a menu
bar and the windows 7 rotating 'busy' doughnut.<br>
<br>
<div class="post-text">This happened after a miktex update. By
selectively updating a MikTex install on a different machine I
narrowed it down to the pstricks update. I uninstalled pstricks
and then reinstalled from the original installation source
(december 2011). Problem fixed.
<p>Code to reproduce:</p>
<pre style="" class="lang-tex prettyprint prettyprinted"><code><span class="kwd">\documentclass</span><span class="pun">[</span><span class="pln">a4paper,twoside,</span><span class="lit">11pt</span><span class="pun">]{</span><span class="pln">book</span><span class="pun">}</span><span class="pln">
</span><span class="kwd">\usepackage</span><span class="pun">{</span><span class="pln">pstricks</span><span class="pun">}</span><span class="pln">
</span><span class="kwd">\begin</span><span class="pun">{</span><span class="pln">document</span><span class="pun">}</span><span class="pln">
Motivation and operation </span><span class="pun">(</span><span class="pln">forced/self-oscillating</span><span class="pun">)</span><span class="pln"> of class-D amplifiers.</span><span class="kwd">\\</span><span class="pln">
</span><span class="kwd">\end</span><span class="pun">{</span><span class="pln">document</span><span class="pun">}</span></code></pre>
<p>Comment out <code>usepackage{pstricks}</code> to 'fix'.</p>
<p>Usually I'm up to date with updates, so it seems this is a new
issue (after december 15 or so) only with the latest
yap/pstricks as of 13/1/2013. Confirmed on 2 machines.</p>
