It appears that in 1.2, you can get into a state where if you call
AmigaBasic, it will start printing all control characters such as <CR> a
O. This makes it unusable. The only way to get out of it is to reload
Kickstart (that's right, resetting Workbench doesn't help). Has anyone
else seen this problem. This is very strange since Kickstart is supposed
to be in a write-protected area in memory…
