Note entry in 6/8 time not helpful

Windows Vista Ultimate 32-bit, MuseScore 0.9.4, revision 1753
Start a score in 6/8 time, attempt to input a dotted quarter note using the mouse: fist click on the rest, then click on the quarter note. Before you have time to click on the dot, the current note is no longer the first note (why???), so you have to click on the first note and then click on the dot.
Rather irritating "feature".
