10.0.4.25 and 10.1.0.45
In SWA when you read an email that has a URL, clicking it has no effect.
The link shows in Firefox 2.0.0.4 in the status bar as "Javascript:void(0)" but if I view source of that frame (the message) it shows the real URL formatted as such in HTML (A href =....)
Also have used Internet Explorer 6.0.2900.2180.xpsp_sp2_gdr.0702227-2254 with the same results.
