Bugs encountered in Musescore

Operating System: Windows XP
Musescore Version: Musescore 0.9.5 r.1667

Key Signature Crash
1. Select "File" and "New"
2. Create any title, subtitle, etc.
3. Add "B flat trumpet" to the instrument list
4. Select any key signature
5. Change the key signature to the key of concert B flat (No sharps or flats) or cut the key signature
6. Musescore crashes
This problem occurs on every instrument whenever I change the key signature so that there are no sharps or flats.

Drum Notation Crash
1. Select "File" and "New"
2. Create any title, subtitle, etc.
3. Add a percussion instrument to the instrument list
4. Select a note or rest within the staff
5. Select "Drums" from the palette.
6. Musescore crashes

Copy and Paste Bug
1. Create a new piece of music with any settings; I used "B flat trumpet"
2. Create a random string of notes and apply slurs
3. Hold "Shift" and select the short composition with the mouse
4. Paste the copied piece of music
5. The slurs are not present in the newly pasted music

Slur Bug
1. Create a new piece of music; I used "B flat trumpet"
2. Create a random string of notes and apply slurs
3. Play the music
4. The slurs are not played; the notes are still articulated
This occurs with many instruments, but the B flat trumpet is very easy to notice

Dynamics Bug
1. Create a new piece of music with any instrument; I used "B flat trumpet"
2. Create a random string of notes
3. Apply noticably different dynamics from "Create" and "Dynamics". I placed "pppppp" on the first note, a crescendo hairpin leading up to "ffffff".
4. Play the composition. The dynamics are not played.

Trill Bug
1. Create a new piece of music with any instrument; I used "B flat trumpet"
2. Create notes long enough to notice a trill
3. Apply trills to the notes
4. Play the composition
5. The trills are not played

Glissando and Tremolo Bug
1. Create a new piece of music with any instrument; I used "B flat trumpet" and "trombone"
2. Create two notes that have many half steps between them; I put two notes two octaves apart
3. Place a glissando between the two notes
4. Play the composition
5. The glissano is not played
The same problem seems to occur with the tremolo

Snare Drum and Bass Drum Bug
1. Create a new piece of music with Snare Drum and/or Bass Drum
2. Place notes within the Snare Drum staff and/or Bass Drum staff by selecting the rest, selecting the "N" for note input, and then entering notes by using the alphanumeric keyboard
3. Either Musescore will crash, or the notes will not be correct. In my case the noises of the Drumset were played instead of a snare or bass drum.

I apologize if I have included any previously mentioned bugs. Despite these minor problems, Musescore is still an excellent music notation software. I congratulate the development team for putting this much effort into Musescore.
