Frequently Asked Question about KlavarScript
It is very important to save regularly. The key "Control-S" does so very quickly and this can prevent loss of a lot of work. Maybe an upcoming version of KlavarScript will save the working file automatically. For now, you have to do this manually.
Resolution to this problem is to quantize the music. You can do so by selecting "Edit > Quantize and trim..." in the menus. The "trim" function will allow you to automatically delete stop signs resulted by staccato playing.
