On our website for this device / OS there is a higher version, 7.3.241.. please install that and see if that corrects the issue you are seeing.. if it does not, please contact Wavelink support..
On 7.3.241 same issue.
Anyway I've noticed same issue at Internet Explorer on my MC9190 Win CE 6.0 without Wavelink.
Im wondering if is it a problem with CE 6.0 (no flash at IE) but not sure if errors messages technology is flash or not.
We are a wrapper to IE on the device.. If the problem is in IE, it would be seen in WIB.. at this point i would contact Motorola for further assistance.
