Looked at numerous helprooms/forums online and many having this problem which is persistent. There were refs pointing to Silverlight as the problem with different fixes. Most common was to uninstall and reinstall. So uninstalled, but before reinstalling tried to forward and send e-mails. Guess what - they both worked! I have no idea why maybe an auto update caused problem. Am carrying on without Silverlight is OK (any info welcome) but will leave alone "if it aint broke dont fix it" I guess.
