[Chameleon] Chameleon 1.99-beta2: ROI Rectangle tool JavaScript error (IE6 SP2)

[Andreas Hocevar]

Hi,

with Chameleon 1.99-beta2 (and also the latest CVS version) in IE6 SP2, 
a doubleclick with activated ROI Rectangle tool causes a JavaScript 
error:

Line: 217
Char: 5
Error: 'null' is null or not an object
Code: 0
URL: http://localhost/ms4w/samples/samples_roi.phtml

This error also occurs in custom applications using the ROI Rectangle 
tool.

Keep up the great work!
Andreas.
