hi guys, one small problem, but kind of annoying.

i use adobe acrobat dc pro as my default pdf viewer, everytime i open a pdf file in tc and when i close adobe acrobat, the tc will freeze for like little a little bit more than 1 seconds and then tc will back to normal. is anyone also have this problem?

thanks!
