128 release draws spurious floodfill

[classilla]

The current 128 release is almost unusable because while handling the "Welcome to Irata" screen, it executes a misfired floodfill that escapes and tries to fill the entire screen.

Slowing it to 2400bps (by manually hacking CONFIG,S since F3 doesn't seem to work on the 128 release) got it a little farther and then it went bad again. This suggests there are corrupted characters coming across. The same T232 works fine in other programs.

This is on a 128DCR, by the way, with 64K VDC. Perhaps this is a scaling problem under the surface.
