Query: Doesn't always work with IE9 and it requires IE.

Have been a customer of theirs for years, and have had a series of software compatability issues, but this last one, as of Mar 2011 is a real kicker . . after I upgraded from IE8 to IE9 (win7 64bit OR 32bit, I tried both) their software stopped working . . after a series of their folks worked with me and their own testing couldn't reproduce the problem, they basically said, "yr on yr own," instead of spending more time with me to isolate the issue, so that OTHER customers don't have the same problem . . I canceled . . . buggy UI, not enough resolve when the problem isn't immediately apparent to their support folks.They have had other similar problem solving technique when in a previous version, they stopped being able to print international labels, I give up . . USPS does the same thing for free and doesn't cost $16 a month.
