I have a weird screen size. Try changing the $str() amount until you get tabbed text off the screen, but not so much that if there weren't tabs but another char it wouldn't be.
The scrollbar is getting updated, but the width seems to be miscalculated as ~80% of the actual width, though I guess that depends on how many tabs are used.
