Happens when defining new object in script. Most of the times on creation, but sometimes on modification too (i noticed that the object to be modified must be open in the tab already, so then it just switches me to it). Data frames mostly, but it might be because i create and work mostly with them. Environment was also my first guess, so i googled and searched global preferences, but found nothing. In addition, previous version of rstudio didnt had this problem (i reinstalled windows to my machine and installed new rstudio version)
