Block specific browser (Chrome, Firefox)

Hi everyone

At our company we are using Workflow to request vacation automaticaly. The problem is, that Worfklow officialy only supports IE and not Chrome and Firefox. We have indeed problems when some user using another browser than IE (for example: the datetime attribut has wrong formation).

So my question is, does Workflow offers an option to read out which browser is used an eventually block them (Warning message or something like this)??

Symantec Workflow Version: 7.1.x

OS: mostly win 7/8

Thanks for your help :-)

Regards

Patrick
