Unable to type Aaaaaaaaaa.

[aiverson]

When attempting to type Aaaaaaaaaa with dasher, the chain subtree for (spaces) can stay at the top of the screen. If I zoom in far enough while maintaining this state, with the cursor in the Aaaaaaaaa region and the (spaces) region onscreen, the software glitches and teleports the point to somewhere closer to the middle of the tree, resulting in selecting a completely different string. Aldage and Ah. Ki occured in my most recent tests.
