[Search Function] search function problem in pdf file

Hello,

I have a problem that the program turns off every time I look for certain characters within a pdf file.

In other words, 'searching function' and windows are in conflict.

- I'm using acrobat 2015 dc. I tried reinstalling, but I have the same problem.

- I also installed Acrobat Reader DC and found the same problem when I used 'Find Text' function.

Belows are Problem signature.
