William Slough,
<div class=""><br class="">
</div>
<div class="">Although I cannot reproduce your problem, I might be able to fix it. I'm preparing a new version of TeXShop with very few changes, but one change might help you. You can download a preliminary version via</div>
<div class=""><br class="">
</div>
<div class=""><span class="Apple-tab-span" style="white-space:pre"></span><a href="https://pages.uoregon.edu/koch/TeXShop470.zip" class="">https://pages.uoregon.edu/koch/TeXShop470.zip</a></div>
<div class=""><br class="">
</div>
<div class="">Let me explain.</div>
<div class=""><br class="">
</div>
<div class="">If several programs are running on your Mac and you want to quit for the night, you can select the menu "Shut Down"</div>
<div class="">A dialog appears, and it has a selectable item reading "Reopen windows when logging back in." If you select this, then the next time you boot your Mac, the programs that were running when you shut down will start running again.</div>
<div class=""><br class="">
</div>
<div class="">One of my users ran into a problem. He typically opened several projects in TeXShop. When the Mac rebooted and TeXShop automatically started, it would get into a loop and have to be aborted. But then when it was started again, it opened without
problems. I could not reproduce this problem.</div>
<div class=""><br class="">
</div>
<div class="">However, I added a fix for him. Version 4.70 has a new hidden preference item named IgnoreStartOnReboot. By default, this preference has value NO and nothing changes. But if you quit TeXShop and then type</div>
<div class=""><br class="">
</div>
<div class=""><span class="Apple-tab-span" style="white-space:pre"></span>defaults write TeXShop IgnoreStartOnReboot YES</div>
<div class=""><br class="">
</div>
<div class="">then when you shut down and ask all your programs to start again on reboot, they will all start except TeXShop. You have to start it manually.</div>
<div class=""><br class="">
</div>
<div class="">I just checked, and this preference also affects Restart. So if you define it to be YES, then when you restart, TeXShop will not restart automatically. (The preference does NOT affect adding TeXShop to the list of Login Items for a user, so you
can still add TeXShop to that list.)</div>
<div class=""><br class="">
</div>
<div class="">Thus this preference changes only two things: if you use Restart, or you shut down your machine and later restart it, all other programs will start again automatically( if you clicked the button on shutdown), but TeXShop won't.</div>
<div class=""><br class="">
</div>
<div class="">-----------</div>
<div class=""><br class="">
</div>
<div class="">Incidentally, I assume that when TeXShop has just a blank window open and you quit it, and then later restart TeXShop, the blank window appears without that second gray window. So I'm assuming the bug only happens with Restart or with shutting
down your machine and then booting it up again at a later time.</div>
