Factory install of windows 10.
I Installed IE11 ver 11.522.214.171.124 update ver 110.0.34
I Installed Acrobat Reader ver 2015.017.20053
IE 11 configured to use acrobat reader plugin
When I open a form fillable pdf in 1E11 with acrobar reader it will usually (always?) open correctly the first time. Then when the form is closed (the IE tab is closed) the next attempt to open the form results in a gray screen (usually). If at this point I use task manager and close one of the two entries for acrobat reader the form will open by itself (grey screen goes away and form is visible).
Further attempts may or may not work, if they do not work I see either a gray screen of the error message to the effect that acrobat reader cannot open, if other copies are open close them and retry.
The error has been seen on windows 7 machines, and windows 10 machines that were upgraded from windows 7 as well. All using IE11.
In a span of 15 minutes I was able to reproduce this error on 4 different machines at 3 different locations (customer's office).
There are times (like now when I tried to get the exact error message) that I cannot make it fail...but this morning a customer was having the error, my employee helping him was having the error, and I was able to get the error...
After closing IE11 often the grey screen will appear, a trip to task manager to close acrobat then things will work for an indeterminate period of time.
In case you were wondering: We are required to use IE11 because we use silverlight and we need acrobat reader because we submit the form - currently the only browser to my knowledge that support silverlight and acrobat plugin are IE8-IE11. Firefox will not use acrobat plugin and chrome will not run silverlight.
Any ideas on what might be causing this?
