Test Case description text box and in Test Suite add a mail text box is not visible to write

This is really a good tool for automation testing, i have an observation.
when i opened to write Test case description i was not able to see what i am writing as the text box is very small not able to expand also.

The same observation i saw at test suite ‘Execution Information’ to add the mail recipients. the text box is not visible to write however what we will write it displays on tool correctly.
