Can you change other things?
If the portal is locked, you can't change anything (not only the number of rows). You can unlock it with
right click > Arrange > Unlock
Hey User 19752
Thx in advance.
The portal is already unlocked. Still i can't change the number of rows
give a screen shot of your project or attach it!
It looks like you have the cursor in the 'Number of Rows' text box in this screenshot. Can you not just type a number? It clearly let you delete the number that was there before.
My bet is that it is somehow keyboard related.
The combination of language, OS, and keyboard, keyboard options.
Something is wrong there.
You just made a test file. Can you post THAT here?
