Needs Answer
When i want to enter a value, f.x. line with a given length, the input field disappears before i can enter a value. I then have to close geogebra, and restart it. then it works for some time, and it happens again. It's really annoying.
The same question 
please send your ggb-file.
What release and what type (classic, web, android, .... etc) you use?
What you mean with "f.x. line with a given length" ? Please give a sample of an input.
