Espresso Desktop Shortcuts open in Chrome but Chrome loads the default search page

[Rawns]

Staff and Students have a Espresso shortcut on their desktops. Their default browser is Chrome however recently, some users find that if they double click the Espresso shortcut, Chrome launches but only opens the default "New Tab" (eg, the Google search page). If the Espresso shortcut is then double clicked again with Chrome still open, the Espresso site does load however in a new tab. I've tried the usual Chrome reset, clear all browsing data, created a new test account etc - all to no avail. It only seems to affect Chrome too as if you change the default browser to IE, Espresso opens immediately.

 

Anyone seen this before?
