Drum palette still crashes

Pianoman1976 asks :

"I wrote music for piano, using Musescore 0.9.5, and when adding a drum line (5 lines), it only allows me to add one or two bars of drumming music before it crashes. I use Windows XP SP2 and I downloaded Musescore version 0.9.5 yesterday (8 February 2010). The same thing happened when I opened a new sheet with only drums (5 lines) as my instrument. I used the palette in both instances, with the same crashing result."
