--- Comment #20 from D Roden winebz@drmm.net 2013-02-15 00:41:39 CST --- TaxAct 2012 says in System Requirements:
"Web Browser: Microsoft Internet Explorer 6.0 or greater" and "Operating System: Windows XP, Vista, Windows 7, Windows 8."
Since TA supports Win7, which IIRC includes IE8, TA should work correctly with IE8 under Wine *if* Wine is fully supporting every IE8 call.
However, under Wine, using IE6 instead eliminates the script error dialogs after each TA Continue or other click.
IE7 seems to produce the same script errors as IE8, but (for me) with blank dialog boxes, much worse, so was not tested further.
I have tried multiple combinations of Wine (1.5.0 to 1.5.23) and IE (6 to 8) for TaxaAct. So far, the most successful combination has been Wine <= 1.5.19 (no Gecko installed) and IE6.
Wine versions > 1.5.19 give rise to bug 32976.
I'm using Puppy 5.25; results may vary with other distros.
To come to the point, no combination of Wine and IE I've yet tried has resolved this bug.
