Variable placeholder in ladder loses focus

Hi,

has anyone else experienced that in the ladder editor - when editing/ inserting variables to contacts, coils, function block inputs, … the placeholder loses focus and needs reenabling/ mouse activation?

While I’m typing variables it just loses focus and as I’m not finishied typing, asking me to create the new variable.
Probably a Windows setting of some sort but I can’t find any.

CoDeSys 3.18.5

Hello,
This seem to be a windows or Codesys problem.
Do you have any other app running at that time?
In codesys do you have autosave/autobackup enabled ?
