There's a big problem with the last version.
The letter disappear when I glide my mouse over them.
It happens with every element who have some text on it. Some screenshot to describe better this problem :
Also it is very hard to edit a label as there is no cursor when in edit mode :
So, I'm forced to use a previous yEd version as this is not possible to work with this one.
Do you have any idea where could be the problem ?
