Hi Kenneth,
 
It indeed is correct that one I disable the borders the error doesn't exists.
but for me this is not an acceptable solutions. We are working with end-users who aren't that technical.
 
Telling them to hit this button if this error exists will probably go well until they haven't used this functionality for a week or something.
Disabling this feature doesn't seems to be a good idea as well, when disabling this feature table layout will become harder for the end users which isn't desired either.
 
Isn't there an other way to fix this issue?
 
I can off course tell the users to use firefox but that isn't really a good solution, I hope there is some other way to solve this.

Thank you ,
