Another "Adobe Reader is already used in another browse window." issue

Hi Adobe Team,

we are getting this following issue, when SAP Users try to open a 2nd PDF File, after  the 1st one opened without a problem

"Adobe Reader is already used in another browse window."

Seems that this problem is a long runner without real answers from Adobes Sitem, besides the usuall BS of Update your Adobe.

Our Adobe Reader  is up-to-date and usually the Updates break most of the time more than they fix things.. just saying.

So could you please be so kind, to have a deeper look and provide an official statement if this is caused by SAP side or by your product & how to fix it (if so)

Thanks & regards,
