Grace Notes too big

Thank-you very much for this excellent software and all your hard work.

When inserting any type of grace note, the grace note is inserted too big (ie; normal note size). If I then adjust the grace note's staff position up or down with the arrow keys, then the size changes to the correct small size. If I then add a slur to the next note, the grace note size will pop back to normal note size.

This occurs on pre-releases since 1619 but pre-release 1598 seems to be OK. I'm running on Windows XP SP3.

If I may, I would like to suggest that bar line be made a little heavier. I realize this may be a matter of taste but I find the current bar lines (including repeats, double bars, etc) to be a bit light.

regards
