version 1.0.5 for windows ,there is the bug:
the buttons in the export dialog, only half is visible. see the screenshot below.
In the latest version the height of the dialog has been shortened. It was submitted recently and should arrive in the plugin manager soon.
The latest version has been released and has a lower height. Also, if you are using tablet that has applications scaled up (Windows tablet default is 150%) please see if setting the scale to 120% helps.
