When I start Groovy Console, the input area is sometimes only one line high (rest of the window is occupied by output area). See screenshot.
After adjusting the size of the input area, it is remembered for a while (across restarts of Groovy Console), until it goes back to one line high after yet another restart. Happens at least once a day. Can't reproduce by quitting and immediately restarting Groovy Console, even if I try several times in a row.
