This is a multi-level issue.
After purchasing and installing Recosoft PDF2ID (a very useful and clever plugin that allows a user to open PDFs right into InDesign), I noticed that InDesign would hang on Quit. Becasue this hang (and my subsequent force-quite maneuvers) became the norm, I decided to disable PDF2ID, the one third party plugin I had added to ID, using the "Adobe Exchange Manager".
After I did that, "magically", ID resumed it's normal quit process; in other words, no more hanging but just a simple, happy and definitely terminal Quit.
I contacted Recosoft and they replied " We have tens of thousands of PDF2ID installations (amongst various users) and this is a first". So, in other words, I should not have an issue myself because other users do not. That's logical, right?
I then decided to enable PDF2ID once more just so I could obtain some sort of crash log on Quit; something I could send Recosoft for them to examine and possibly find the problem.
When I did enable the plugin again (Exchange screen below, last item enabled), I got a "Startup Alert" -also attached.
Only one time, the plugin loaded and, as expected, ID hang on Quit.
After that I could not get the plugin to load again (but got more "Startup Alerts").
I emailed Recosoft again and send them the Force-Quit log. they told me that they saw no issues and, furthermore, they added "You should contact the Adobe Exchange store to download it and install it again.".
After spending 2 useless hours with Adobe on the phone, they told me (in an email I asked them to send me) that "The plugin is from Recosoft & not from Adobe, we have helped you [not true at all] with the installation & activation of the plugin but we cannot help you with the usage of the plugin." I never asked them to help me with the usage of the plugin. I asked them to help me reinstall a plugin that I had purchased through Adobe Exchange, a function that apparently Exchange cannot perform.
So, I purchased a plugin using Adobe Exchange. The plugin somehow went bad and impairs the normal functioning (quit, to be precise) of InDesign. Recosoft won't help because I bought their plugin through Adobe Exchange and Adobe won't help either (but is happy to send me an email with a lie embedded in it) because it is not their plugin ... Who should I call now? Apple because I'm using a Mac? The manufacturer of the chair where I sit while I work?
Maybe they are the ones who are supposed to help me get a replacement plugin installed. You tell me.
