Hey Max,
There's an error in IE7 when the sprite tries to set the bgcolor of a div to
be a value that looks like a combination of a hex value plus a float, for
example
#f9f9f93700.00014
This value is coming from the swatchview setting a bgcolor which has an
alpha
value (e..g., rgb.0a format decimal)
Is that weird hybrid hex/decimal format actually a supported color CSS spec,
or does it just happen to work in Firefox. IE7 will not accept it. Do you
know what the right way to handle this case is (alpha with bgcolor)?

Henry Minsky commented on LPP-8524:
-----------------------------------
The error is happening because a color is being passed in to setbgcolor
which is a floating point number, and LzColorUtils.inttohex turns that into
a bogus string. Now, to figure out where that is coming from...
